+% \maketitle
+% \begin{documentation}
+% This module generates a generic driver for \pkg{hyperref} meant to be used
+% with the new \LaTeX{} PDF management code. It is loaded automatically
+% if the PDF management code is active. The name of the driver will change after
+% the testphase.
+%
+% The generic driver can be used with pdflatex, lualatex, xelatex, latex with
+% dvipdfmx, latex with dvips+ps2pdf. latex with dvips+distiller could work too
+% but is untested. (x)dvipdfmx will probably soon support dvilualatex, then this
+% combination should work too.
+%
+% The driver \emph{requires} the new PDF management code, so documents wanting to use it
+% should start like this
+% \begin{verbatim}
+% \RequirePackage{pdfmanagement-testphase} %loads the code
+% \DeclareDocumentMetadata % activates it
+% {
+% %% options
+% %% e.g. pdf version, backend:
+% % pdfversion=1.7,
+% % backend = dvipdfmx
+% }
+% \end{verbatim}
+%
+% The new driver tries to be compatible with the standard \pkg{hyperref} drivers
+% but there are nevertheless differences. Some of them due to the still experimental
+% status of the driver, others are design decisions: one part of the project is
+% to clean up and modernize the code. The following sections try to describe
+% the differences but also to document some of the rationales of the changes,
+% and to add some details and comments about the existing options and so to
+% extend the \pkg{hyperref} manual.
+%
+% \section{Avoiding transition problems}
+% Some code will only work properly after other packages have been adapted to
+% the new PDF management code and the changes in this driver.
+% This will take some time. Until then it is recommended to follow
+% the following rules
+% \begin{itemize}
+% \item Package options are processed at the end of the driver,
+% Class options are ignored. But not every option already works as package options,
+% in some cases \pkg{hyperref} interferes. So
+% it is recommended for most options ---with the exception of a few mentioned below in
+% section~\ref{sec:pkg-options}---to set them in \cs{hypersetup},
+% not as package option.
+% \item This driver uses \pkg{l3color} for the colors. All colors
+% defined with \cs{color_set:nn} or \cs{color_set:nnn} will work.
+% Colors defined with \pkg{xcolor} will work if they don't use one of
+% the special color models not supported by \pkg{l3color} as
+% \pkg{pdfmanagement-firstaid} contains a patch for xcolor.
+% If the package \pkg{color} is used it is currently recommended to define
+% colors after \pkg{hyperref}. This driver uses \pkg{l3color} for the colors,
+% some special color models of \pkg{xcolor} won't work.
+% \item Load a color package or graphicx to get the right page sizes.
+% \item Report problems! Only known problem can be resolved.
+% \end{itemize}
+%
+%
+% \section{Bookmarks / outlines}
+% The new driver doesn't contain code to handle bookmarks/outlines.
+% Instead it forces the loading of the \pkg{bookmark} package
+% unless the package option |bookmarks=false|
+% has been used. Currently \pkg{bookmark} is loaded at the end of the preamble
+% so if commands from \pkg{bookmark} are needed in the preamble the document
+% should load it manually. This is subject to change at some time in the future.
+%
+% \section{\enquote{Metadata}}
+%
+% \enquote{Metadata}, informations about the document, are stored in a PDF in two
+% places: The |/Info| dictionary and the XMP-metadata. \pkg{hyperref} only handles the
+% |/Info| dictionary. The XMP-metadata can be added with like \pkg{pdfx} and
+% \pkg{hyperxmp}.
+%
+% The |/Info| dictionary can be filled with arbitrary keys, but the PDF viewer typically
+% care only about a few, like |/Author|, |/Title| and |/Keywords|.
+% A number of |/Info| keys, like dates and the producer, are added automatically
+% by the engines and backends.
+% Some of them can only be removed with special commands, some not at all.
+% But---with the exception of |/Producer| when using the dvips backend---they
+% can be overwritten.
+%
+% The current handling of the metadata is problematic:
+% \begin{itemize}
+% \item External package like \pkg{hyperxmp} wants to access them too and for
+% this had to patch an number of internal hyperref commands---which is a problem
+% if the internal commands change (as happens with this new driver)
+% \item \pkg {hyperref} (and also \pkg{hyperxmp})
+% tries to deduce some datas from document commands like
+% \cs{title} or \cs{author}---something that worked reasonably well when only
+% some standard classes with well-known definitions of these command existed,
+% but gets problematic with classes and packages which define
+% more powerful commands knowing a variety of optional arguments to set authors and
+% affiliations and title information.
+% \end{itemize}
+%
+% To resolve some of this problem the driver will
+% \begin{itemize}
+% \item \emph{Not} try deduce author and title from documents. They have to be set in
+% \cs{hypersetup} with |pdfauthor| and |pdftitle|. It is recommended to separate
+% more than one author by commas, and to hide commas inside braces if needed:
+%
+% \begin{verbatim}
+% pdfauthor = {Bär, Peter Anteater, {Riley, the sloth}}
+% \end{verbatim}
+% \item All values of relevant keys (including keys from the hyperxmp package)
+% will be stored in a Metadata container, and can be retrieved with
+% \cs{GetDocumentProperties}.
+%
+% \begin{verbatim}
+% \edef\my@pdfauthor{\GetDocumentProperties{hyperref/pdfauthor}}
+% \end{verbatim}
+% If the key hasn't be set, the result is empty. This gives external
+% packages a public and reliable access to the data.
+%
+% \item |pdflang| is deprecated. Instead \cs{DeclareDocumentMetadata}
+% should be used:
+% \begin{verbatim}
+% \DeclareDocumentMetadata{lang=de-DE}
+% \end{verbatim}
+%
+% The value can be retrieved as |document/lang|.
+%
+% \end{itemize}
+% \section{Dates}
+% \pkg{hyperref has a few keys to set dates}. They typically expect the date
+% in \enquote{PDF} format: |D:YYYYMMDDhhmmss+01'00'|.
+%
+% One should be aware that \pkg{hyperxmp} will sometimes
+% overwrites such settings.
+% ^^A XMP: yyyy-mm-ddThh:mm:ss+tt:tt, PDF: D:YYYYMMDDhhmmss+01'00'
+%
+% \section{PDF page size (mediabox)}
+% The standard \pkg{hyperref} driver contain code to set the PDF page size.
+% There is no real justification why this is done by \pkg{hyperref} apart from the
+% fact that \LaTeX{} itself doesn't do it and that the needed special code could
+% be added to the backend drivers.
+%
+% In the new driver this code is gone. The reason is not that it is
+% difficult to set the MediaBox, actually it could be done with one line of code:
+% \begin{verbatim}
+% \pdfmanagement_add:nnn{Page}{MediaBox}
+% {[0~0~\dim_to_decimal_in_bp:n{\paperwidth}~
+% \dim_to_decimal_in_bp:n{\paperheight}]}
+% \end{verbatim}
+%
+% The problem is to know which value to use (with the memoir class e.g.\cs{stockwidth}
+% should be used instead of \cs{paperwidth}),
+% and detecting this not a \pkg{hyperref} task. Instead the packages which change
+% these values should also set the PDF page size. Also there are
+% too many actors here: color/graphicx, geometry,the KOMA-classes, memoir,
+% \ldots\ all try to set this.
+%
+% So if the PDF page size is wrong: load one of the other packages setting it
+% e.g. the \pkg{color} or the \pkg{graphicx} package.
+%
+%
+% \section{Link decorations: border, color, OCG-color, \ldots}
+% Some main changes are
+% \begin{itemize}
+% \item The default colors have been changed.
+% \item |citecolor| is no longer set with |allcolors| and it is not part of the
+% color scheme, it is only supported for compability.
+% \item a number of color schemes have been predefined.
+% \end{itemize}
+%
+% \subsection{Background information}
+% With the standard drivers \pkg{hyperref} allows either to color the link text,
+% or to use a border around it.
+% There is also a (rather unknown) option |frenchlinks| to use small caps
+% for some links instead of colors.
+%
+% The \emph{link border} is a setting in the PDF annotation directory.
+% It can be colored and styled (with the |bordercolor|, |pdfborderstyle|
+% and |pdfhighlight| keys), but the exact look depends on the PDF viewer.
+% Such decorations are normally not printed.
+%
+% The \emph{link text} is colored with the standard color commands for text.
+% Such a color is also printed, which is often not wanted. The printing
+% can be avoided in PDF with so-called OCG-layers: They allow to add
+% variants of a text along with instructions which variant should be used for
+% viewing and which for printing. \pkg{hyperref} implements a rather simple version
+% for links: The link text is put in a box and printed twice with different colors
+% on different OCG layers. As boxes are used such links can't be broken. The
+% package \pkg{ocgx2} implements a more sophisticated version which allows to
+% use it for links broken over lines and pages.
+%
+% \pkg{hyperref} has keys to set the color and border for |link|, |url|, |file|,
+% |menu| and |run| types. They correspond to the PDF annotation types
+% |GoTo|, |URI|, |GoToR|, |Named| and |Launch|.
+% Beside this there is a |anchorcolor| which isn't used at all, and |citecolor|
+% which is a semantical category and doesn't fit to the other types.
+%
+% In the standard drivers the decoration options are more or less exclusive and global:
+% One of the options (|colorlinks|, |ocgcolorlinks|, or borders) has to be
+% chosen in the preamble and is then used for the whole document
+% and all link types.
+% Only colors and eventually the border style can be adjusted locally.
+% But there is no technical reason for these restrictions:
+% It is quite possible to change all these attributes
+% at any time both by link type and locally. The restrictions of the current
+% implementation can only be explained by the age of the code: \pkg{hyperref}
+% has been created at a time when memory was small and the main drivers were html
+% and postscript based.
+%
+% While link colors have been traditionally more or less
+% under the control of \pkg{hyperref},
+% the situation with other format options, like the font, is more complicated.
+% The font in \cs{url} is for example determined by \cs{Urlfont},
+% a command from the \pkg{url} package.
+% In the case of internal (GoTo) references packages like \pkg{cleveref} or
+% \pkg{biblatex} or \pkg{glossaries} offer formatting options too.
+% Formatting here is often connected to semantics:
+% an acronym should use a different font than a citation.
+% While \pkg{hyperref} could offer options here, it would probably only clash
+% with package formatting. It is more sensible not to interfere here. For this
+% reason the |frenchlinks| option has been dropped.
+%
+% \subsection{New Keys}
+% Some of the existing keys have been extended to allow individual setting for
+% the link types |link|, |url|, |file| |menu| and |run|:
+%
+% \begin{itemize}
+% \item Beside |pdfborder| there are also |linkborder|, |urlborder| etc
+% \item Beside |pdfhighlight| there are also |linkhighlight|, |urlhighlight| etc
+% \item Beside |pdfborderstyle| there are also |linkborderstyle|, |urlborderstyle| etc
+% \item Beside |colorlinks| there are also |colorlink|, |colorurl| etc
+% \item Beside |ocgcolorlinks| there are also |ocgcolorlink|, |ocgcolorurl|, etc %TODO
+% \item Beside |hidelinks| there are also |hidelink|, |hideurl|, etc
+% \item |bordercolormodel| allows to set the model used in annotations,
+% the allowed values are |rgb| or |cmyk|. |rgb| is the default.
+% It does \emph{not} change the model of text colors. Be aware
+% that while the PDF format allows cmyk (4 numbers) in the |/C| key of an annotation,
+% this is often ignored by pdf viewers and the colors can be wrong.
+% \item The boolean keys |url|, |link|, |run|, |menu|, |file| allow to deactivate
+% locally the link types.
+% \end{itemize}
+%
+% \begin{hypkey}{colorscheme}
+%
+% The new key |colorscheme| allows to switch the colors (both for text and borders)
+% with a key word. It takes one of the values
+% |orginal| (the colors as hyperref uses normally), |phelype|, |daleif|,
+% |szabolcsA|, |szabolcsB|, |tivv|, |julian|, |henryford|.
+%
+% The names refer to the authors in answers and comments in
+% \url{https://tex.stackexchange.com/questions/525261/better-default-colors-for-hyperref-links}.
+%
+% The default is |phelype|.
+% \end{hypkey}
+%
+% \subsection{Public interfaces}
+% The |colorlinks| and |ocgcolorlinks| and related keys are
+% using these booleans:
+% \begin{verbatim}
+% \l_hyp_annot_colorlink_bool,
+% \l_hyp_annot_colorurl_bool,
+% \l_hyp_annot_colorfile_bool,
+% \l_hyp_annot_colorrun_bool,
+% \l_hyp_annot_colormenu_bool,
+% \l_hyp_annot_ocgcolorlink_bool,
+% \l_hyp_annot_ocgcolorurl_bool,
+% \l_hyp_annot_ocgcolorfile_bool,
+% \l_hyp_annot_ocgcolorrun_bool,
+% \l_hyp_annot_ocgcolormenu_bool,
+% \end{verbatim}
+%
+% They are both inserting hook code in the |pdfannot/link/|\meta{type}|/begin|
+% and |pdfannot/link/|\meta{type}|/end| hooks. \meta{type} is one of
+% |GoTo|, |URI|, |GoToR|, |Named| or |Launch|.
+%
+% |colorlinks| uses the label |hyp/color|, and |ocgcolorlinks| the label |hyp/ocg|.
+%
+% They both use the same color names: |hyp/color/link|, |hyp/color/url|,
+% |hyp/color/file|, |hyp/color/run|, |hyp/color/menu|.
+%
+% The cite colors uses the names |hyp/color/cite| and |hyp/color/citeborder|.
+%
+% The border colors aren't saved in color names currently, but if the need
+% would arise it would possible to change this.
+% \subsection{Changed behaviour}
+% \begin{description}
+% \item[colorlinks] |colorlinks| will as before disable the |pdfborder|, but it is possible
+% to use the key in the document at any time, or to reenable the border if wanted.
+% Internally |colorlinks| \& friends will no longer define/undefine
+% |\Hy@colorlink|, but instead use the hooks provided by the \pkg{l3pdfannot} package.
+% \item Color keys accept the following input syntax:
+%
+% \begin{tabular}{ll}
+% model based & |urlbordercolor = [rgb]{1,1,0}| \\
+% color expression & |urlbordercolor = red!50!blue| \\
+% command & |urlbordercolor = \mycolor|
+% \end{tabular}
+%
+% where |\mycolor| should expand to one of the other two syntax variants.
+%
+% \item[frenchlinks] The option |frenchlinks| does nothing at all.
+% \item[cite colors] As mentioned above the support for |citecolor|
+% and |citebordercolor| has been reduced. A package like \pkg{hyperref}
+% can't keep track of such semantic
+% contexts like cite, acronym, glossaries and special references and maintain keys for
+% them. The keys are not completly dropped as this would affect packages like
+% \pkg{natbib}, but they have been separated and are no longer affected by
+% group keys like |allcolors| but must be set individually instead.
+%
+% \item[link margin] The driver sets a default link margin---this is identical
+% to pdftex and luatex driver, but a change for the xetex and dvips driver.
+% The (undocumentated) command \cs{setpdflinkmargin} does nothing.
+% Use either the key |pdflinkmargin| or \cs{pdfannot_link_margin:n} to change the margin.
+% See also the description in section~\ref{sec:keydesc} and in the hyperref manual.
+% \end{description}
+%
+% \section{PDF strings}
+%
+% \pkg{hyperref} uses a command called \cs{pdfstringdef} to convert text input into
+% something that makes sense and is valid in a PDF string, e.g. in the bookmarks
+% or in the info dictionary or as form field values.
+%
+% As the handling of the outlines are delegated to the \pkg{bookmark} package, they
+% will for now still use \cs{pdfstringdef}, but all other strings produced by
+% this driver will use a new method based on the expl3 commands
+% \cs{text_purify:n} and \cs{str_set_convert:Nnnn}. For normal text
+% it shouldn't matter, but a variety of commands and math are handled differently.
+% Like with \cs{pdfstringdef} they are a number of ways to adjust the outcome of
+% \cs{text_purify:n}. These are described in the expl3 documentation interface3.pdf.
+%
+% \emph{The new method is under heavy development!}
+%
+% Important differences here are
+% \begin{itemize}
+% \item \emph{This new method requires that files are utf8-encoded}
+% (at least if non-ascii chars are used in for PDF strings).
+% \item \emph{All} robust commands are currently removed,
+% unless an equivalent has been declared.
+% \item Currently the new method is much more silent: it doesn't warn like
+% \pkg{hyperref} if it removes commands.
+% \end{itemize}
+%
+% \section{Package options from hyperref}\label{sec:pkg-options}
+% The driver will process the package options at the end.
+% But normally options should better be set with \cs{hypersetup} after
+% the package has been loaded. This is also the case for options which normally
+% don't work in \cs{hypersetup}.
+% One option that currently doesn't work correctly as package option is
+% |ocgcolorlinks|
+%
+%
+% Options that still must be set as package options are
+% \begin{itemize}
+% \item |backref|
+% \item |CJKbookmarks| this key should not be used anymore. At some time
+% it will be removed.
+% \item |destlabels| (destination names are taken from \cs{label} if possible)
+% \item |encap|
+% \item |hyperfigures| (according to the \pkg{hyperref} manual
+% it makes figures hyper links, but actually is a no-op for most drivers, and it
+% does nothing with this driver either.)
+% \item |hyperfootnotes|
+% \item |hyperindex|
+% \item |implicit| (redefine \LaTeX\ internals)
+% \item |nesting| unneeded key, see comment below in \ref{sec:keydesc}. At some time
+% it will be either removed or extended (if some use can be found).
+% \item |pagebackref|
+% \item |pdfpagelabels| (set PDF page labels)
+% \item |psdextra| this loads some extra definitions used by \cs{pdfstringdef}.
+% The new driver uses \cs{pdfstringdef} only for the bookmarks, for other strings
+% it is not relevant.
+% \end{itemize}
+%
+% Options that can be without problems set as package options are
+% \begin{itemize}
+% \item |debug|, |verbose| (a boolean)
+% \item |bookmarks| (a boolean)
+% \item |plainpages|
+% \item |draft|, |final|
+% \item |hypertexnames|
+% \item |naturalnames|
+% \item |pageanchor|
+% \end{itemize}
+%
+% Ignored options:
+% \begin{itemize}
+% \item All driver options like |pdftex|, |dvipdfmx|, \ldots
+% \item |raiselinks| (only used in the dviwind, textures and tex4ht driver anyway)
+% \item |frenchlinks|
+% \item |setpagesize|
+% \item |addtopdfcreator|
+% \end{itemize}
+%
+% \section{Disabling links}
+%
+% \pkg{hyperref} knows like many packages the options |draft| and |final|.
+% With \pkg{hyperref} they can be used as package options or in the preamble
+% in \cs{hypersetup} and disable links and anchors completely.
+% The new driver passes the options also to the \pkg{bookmark} package if
+% \pkg{bookmark} hasn't been loaded yet as bookmarks can't work properly if
+% the anchors from hyperref are missing.
+%
+% \DescribeHypkey{link}%
+% \DescribeHypkey{url}%
+% \DescribeHypkey{file}%
+% \DescribeHypkey{run}%
+% \DescribeHypkey{menu}%
+% The |draft| option is a global option that can't be undone (at least not easily).
+% So the new driver offers also boolean keys |link|, |url|, |file|, |run| and |menu|
+% which allow to locally disable a link type. So e.g.
+% |\hypersetup{link=false}\ref{abc}| will give a reference without link (this
+% is naturally also possible with |\ref*{abc}|). This disables also all hooks of
+% the link type, so the link is for example no longer colored. It also removes the
+% implicit grouping of the content.
+%
+%
+% \section{Draftmode}
+% pdftex and other engines knows a
+% draftmode which can be set with |\pdfdraftmode=1|
+% and \pkg{hyperref} honors this in some places. The new
+% driver ignores it, for example |pagelabels| are created in any case.
+% With today's computer power there is not much to gain and it only complicates
+% the code.
+%
+% This should not be confused with the |draft| and |final| package options! They
+% are still honored.
+%
+% \section{Dropped options}
+% A number of options are ignored by this driver
+% \begin{description}
+% \item[pdfversion] The pdfversion should be set in \cs{DeclareDocumentMetadata}
+% \item[setpagesize] The key is ignored and the PDF page size is not
+% set. Load \pkg{color} or \pkg{graphicx} or use a class which sets the PDF page size.
+% \item[breaklinks] The option does nothing sensible anyway (apart from triggering
+% a warning). Currently with latex+dvips links can't be broken. But there is work
+% in progress to change this.
+% \item[unicode] This is always true.
+% \item[pdfa] If this option is set to true \pkg{hyperref} normally checks and sets
+% a small number of requirements for the PDF standard PDF/A.
+% The key is ignored with this driver. Instead the wanted standard should be declared
+% in \cs{DeclareDocumentMetadata}:
+% \begin{verbatim}
+% \DeclareDocumentMetadata{standard=A-2b}
+% \end{verbatim}
+% Currently |A-1b|, |A-2b|, |A-3b| can be set.
+% The support for various requirements is still incomplete, but the parts that
+% \pkg{hyperref} checked are implemented:
+% \begin{itemize}
+% \item The |/F| key is added to links and |Print| is activated, |Hidden|, |Invisible|,
+% |NoView| are deactivated.
+% \item |/NeedAppearances| is suppressed
+% \item Pushbuttons, which use the action |/S/JavaScript| are suppressed.
+% \item Resetbuttons, which use the action |/S/ResetForm| are suppressed.
+% \item In widget annotations, the /AA dictionary is suppressed.
+% \end{itemize}
+% \end{description}
+% \section{Destinations}
+% Destinations (sometimes call anchors in the \pkg{hyperref} documentation)
+% are the places a link jumped too. Unlike the name may suggest they don't described
+% an exact location in the PDF. Instead a destination contains a reference to
+% a page along with an instruction how to display this page.
+% The normally used \enquote{XYZ \textit{top left zoom}} for example instructs
+% the viewer to show the page with the given \textit{zoom} and
+% the top left corner at the \textit{top left} coordinates---which then gives
+% the impression that there is an anchor at this position.
+%
+% From these instructions two (|Fit| and |FitB|) don't take an argument.
+% All others take one (|FitH|, |FitV|, |FitBH|, |FitBV|)
+% or more (|XYZ|, |FitR|) arguments. These arguments are normally
+% coordinates, |XYZ| takes also a zoom factor. The coordinates are
+% absolute coordinates in |bp| relative to the lower left corner
+% of the PDF.
+%
+% With the primitive command \cs{pdfdest} of pdftex almost all instructions are created
+% with a keyword only: The needed coordinate is calculated automatically from the location
+% the \cs{pdfdest} command is issued. So to get a specific coordinate one has to
+% move the command to the right place. E.g.
+% \begin{verbatim}
+% \AddToHookNext{shipout/background}
+% {\put(0,-\pdfpageheight+100bp){\pdfdest name{destA} FitH\relax}}
+% \end{verbatim}
+%
+% Exceptions are the |XYZ| instruction, where pdftex accepts a keyword
+% |zoom| followed by a zoom factor, and the |FitR| instruction
+% which understands the keywords |width|, |height| and |depth|
+% followed by a dimension, which is then used to calculate a rectangle relative to the
+% current location. If no keywords are given the dimensions are taken from the surrounding
+% box---which can also lead to zero sized areas.
+%
+% The manual of \pkg{hyperref} gives a bit the impression as if this
+% coordinates can be set manually by the user but as described above this is
+% mostly wrong: It is for normal destination only possible with a dvi-backend like
+% dvips which make use of |pdfmark.def|. pdftex and luatex can use manual coordinates
+% only for |pdfstartview| and |pdfremotestartview|.
+% As dvips was the first driver of \pkg{hyperref} the option |pdfview| was at first
+% developed for it and then adapted to pdftex. But this had the effect that the handling
+% of the option |pdfview| is inconsequent across the backend and engines:
+% For example with |pdfview=FitH 100| pdftex ignores the
+% number and calculates its own, while dvips sets the coordinate to the absolute
+% 100. The zoom factor of |XYZ| is not supported by the pdftex driver at all, and
+% |FitR| only partially.
+%
+% The generic driver consolidate this but tries to stay compatible with the other
+% drivers as far as possible.
+% It also takes into account that |pdfview| and |pdfstartview| and |pdfremotestartview|
+% have different requirements: While for the first relative coordinates are fine,
+% for the two others absolute coordinates are more sensible.
+%
+% \DescribeHypkey{pdfview}
+% \DescribeHypkey{pdfstartview}
+% \DescribeHypkey{pdfremotestartview}
+% So with this driver the options
+% |pdfview|, |pdfstartview| and |pdfremotestartview| take
+% the following options:
+% \begin{itemize}
+% \item |Fit|, |FitB|, |FitH|, |FitV|,
+% |FitBH|, |FitBV| which can be followed by a positive integer (separated by a space) or the
+% keyword |null|.
+% The number can be gives as a \meta{dimension expression} surrounded with
+% \cs{hypercalcbp}. The driver redefines this command to use
+% \cs{dim_to_decimal_in_bp:n}.
+% \begin{itemize}
+% \item |pdfview| will ignore the integer and any other arguments and calculate
+% the expected coordinates as described above for pdftex with all
+% supported engines and backends.
+% \item |pdfstartview| and |pdfremotestartview| will pass the optional
+% number or keyword after expansion as absolute coordinate. Missing numbers will
+% be filled up with |null|.
+% \end{itemize}
+%
+% \item |XYZ|. This can be followed (separated by spaces) by up to three
+% positive integers or keywords |null| which are then taken as \textit{top left zoom}
+% in this order. \textit{zoom} is a factor, so e.g. 0.5 will give a scaling of 50\%.
+% \begin{itemize}
+% \item |pdfview| will use the last value as \textit{zoom}, ignore all other values
+% and calculate the expected coordinates as described above for pdftex with all
+% supported engines and backends (this means it is possible to use |XYZ 2| to
+% set a zoom of 200\%, it is not necessary to fill in dummy values.)
+% \item |pdfstartview| and |pdfremotestartview| will pass the optional
+% numbers or keyword after expansion as absolute coordinates and zoom.
+% Missing numbers will be filled up with |null|.
+% \end{itemize}
+% This new behaviour is in part incompatible with previous handling with the dvips driver.
+%
+%
+% \item |FitR|.
+% If no argument (separated by spaces) follows then
+% |pdfview| will use with pdftex and luatex
+% the automatic calculation of the coordinates from the encompassing box. With
+% dvips and (x)dvipdfmx it will fall back to |Fit|.
+% |pdfstartview| and |pdfremotestartview| will fallback to |Fit| too.
+%
+% If arguments (separated by spaces) follow they should be
+% four numbers representing \texttt{left bottom right top}.
+% \begin{itemize}\item
+% |pdfview| will use the values to calculate coordinates relative to the current
+% location. So |0 -100 200 400| will give a \enquote{box} of width 200bp,
+% height 400bp and depth 100dp that the destination should encompass.
+% Missing numbers will be set to 0. But one should be aware that is it is quite
+% unpredicable how viewers which support |FitR| handles zero sizes.
+%
+% \item |pdfstartview| and |pdfremotestartview| will pass
+% the values as absolute coordinates.
+% \end{itemize}
+% \end{itemize}
+%
+%
+%\section{Assorted key descriptions}\label{sec:keydesc}
+%The following gives a few details to some keys that are perhaps not
+%completly described in the manual, or are a bit different in this driver.
+%The list is alphabetic.
+%
+% \DescribeHypkey{bookmarkstype} This key takes as value the extension of a list
+% like |toc| or |lof|. If this list uses \cs{addcontentsline} the content will
+% be added to the bookmarks. The key can be use in \cs{hypersetup} and also in
+% the middle of the document to switch the list.
+%
+% \DescribeHypkey{bordercolormodel} With |bordercolormodel| the colormodel used in the |/C|
+% key of the annotation array and in similar keys is set. It does not affect
+% the text and graphics colors in the page stream.
+% Possible choices are |rgb| (three numbers in the array) and |cmyk| (four numbers).
+% While the PDF reference allows four numbers, PDF readers don't necessarly handle
+% this correctly, so the value can be wrong.
+%
+% \DescribeHypkey{destlabel} This is a boolean key. Currently it must be set
+% as package option. If set to true, the name
+% of a destination is taken from a following \cs{label}, if there is one before
+% the next destination command. This requires two compilations to get
+% the correct coordinates in the destination. In the first compilation
+% the alias name is recorded in the aux-file:
+% \begin{verbatim}
+% \hyper@newdestlabel{section.1.2}{sec:sec2}
+% \end{verbatim}
+% The next compilation can then make use of it.
+% The two-pass could be avoided in the future with a better labeling system,
+% where the name if set earlier.
+%
+% \DescribeHypkey{extension} This key sets an variable that has two purposes:
+% It is used if file name has not extension, and it decides if the annotation
+% is a URI or GoToR annotation. So
+% \begin{verbatim}
+% \hypersetup{extension=dvi}
+% \href{mwe1.pdf}{pdf}
+% \href{mwe2.dvi}{dvi}
+% \href{mwe3}{no ext}
+% \end{verbatim}
+% will create
+% \begin{verbatim}
+% /Subtype/Link/A<>
+% /Subtype/Link/A<>
+% /Subtype/Link/A<>
+% \end{verbatim}
+% Typically PDF viewer can handle only GoToR annotions pointing to a PDF.
+% So normally the default value |pdf| of this key should not be changed.
+% \DescribeHypkey{nesting}\label{key:nesting}%
+% This key is useless in PDF context. The boolean is only used in
+% the code for anchors/destination where nesting doesn't make sense.
+% It should not be changed.
+%
+% \DescribeHypkey{pdfborder}\DescribeHypkey{linkborder}\DescribeHypkey{urlborder}
+% \DescribeHypkey{runborder}\DescribeHypkey{menuborder}
+% This key set accept as value three numbers or three numbers and an array describing
+% a dash pattern, examples are |0 0 1| or |0 0 1 [3 2]|.
+% The first two numbers should according to the reference set round
+% corners, but PDF viewer seem to ignore it. The third number is the line width
+% of the border. Settings done with |pdfborderstyle| should take precedence.
+%
+% \DescribeHypkey{pdfborderstyle}\DescribeHypkey{linkborderstyle}
+% \DescribeHypkey{urlborderstyle}\DescribeHypkey{fileborderstyle}
+% \DescribeHypkey{runborderstyle}\DescribeHypkey{menuborderstyle}
+% The value of this key is the content of the |BS| dictionary.
+% As an example |/Type/Border /W 1 /S/U /D[3 2]|
+%
+% \begin{tabular}{>{\ttfamily} lll}
+% Key & Values & comment / example\\\hline
+% /Type & |/Border| & optional \\
+% /W & \meta{number} & Width of border line \\
+% /S & |/S| & solid (default)\\
+% & |/D| &dash pattern can be set with /D\\
+% & |/B| & beveled\\
+% & |/I| & inset\\
+% & |/U| & underline\\
+% /D & \meta{array of numbers} & dash pattern (lines/gaps) (default [3])
+% \end{tabular}
+%
+% \DescribeHypkey{pdfcreationdate}\DescribeHypkey{pdfmoddate}
+% Setting these keys is normally not needed. If they are used the values
+% are stored directly in the Info dictionary for |/Creationdate| and |/ModDate|.
+% The values are converted to strings but not processed further, so they should
+% have the correct PDF format without the enclosing parentheses,
+% e.g. |D:20200202111111+01'00'|.
+%
+% \DescribeHypkey{pdflinkmargin}As described in the \pkg{hyperref} manual
+% the behaviour differs between the backends: with dvips it is possible to
+% change links locally, pdflatex and lualatex work by page, with dvipdfmx
+% the setting is global (and has to be done in the preamble).
+%
+% \DescribeHypkey{pdflang} The key will work, but it is recommended to the set
+% the language in \cs{DeclareDocumentMetadata} instead.

+% \section{Compability commands}
+% \subsection{Metadata}
+% A number of values should be accessible from other packages. Until now
+% packages like \pkg{hyperxmp} used variables like \cs{@pdfauthor}. As they are
+% gone we need to provide some other access.
+% \begin{macrocode}
+\cs_new_protected:Npn \@@_store_metadata:nn #1 #2 %#1 key, #2 value.

+ }
+\cs_generate_variant:Nn \@@_store_metadata:nn {xn,nx,xx}
+% \end{macrocode}
+% \subsection{citecolor}
+% cite is a link context. So we define a hook, and the keys in terms of this hook.
+%
+% \begin{macrocode}
+\hook_new:n{hyp/link/cite}
+\color_set:nnn {hyp/color/cite}{HTML}{2E7E2A}

+ {
+ \keys_set:nn { hyp / setup }
+ {
+ ,linkbordercolor= hyp/color/citeborder
+ ,linkcolor = hyp/color/cite
+ }
+ }
+% \end{macrocode}
+% \section{Checks}
+% The driver can not work properly if the pdfmanagement is not active,
+% as keys need to write to the catalog and to info. But annotations
+% and outlines should work.
+% So should this be a fatal error?
+% Should there be a difference between missing and inactive management?
+% TODO
+% \begin{macrocode}
+\bool_lazy_and:nnF
+ { \cs_if_exist_p:N \pdfmanagement_if_active_p: }{ \pdfmanagement_if_active_p: }
+ { \msg_error:nn { hyp}{ missing-resource-management } }
+% \end{macrocode}
+% Outlines/bookmarks require the bookmark package.
+% TODO check pdfpagemode if booksmarks are suppressed.
+% \begin{macrocode}
+\legacy_if:nT { Hy@bookmarks }
+ {
+ \AddToHook{begindocument/before}[hyperref/bookmark]{\RequirePackage{bookmark}}
+ }
+\legacy_if:nT {Hy@draft}
+ {
+ \PassOptionsToPackage{draft}{bookmark}
+ }
+% \end{macrocode}
+%
+% \section{Reference and label commands}
+% The code uses the l3ref-tmp package which
+% must have been loaded as pdfmanagement is a requirement.
+% The commands use after the module prefix always |_ref|.
+%
+% At first a label command which add the space commands from LaTeX:
+% \begin{macro}
+% {
+% \@@_ref_label:nn,
+% \@@_ref_if_exist:nn,
+% \@@_ref_check:nn,
+% \@@_ref_value:nn
+% }
+% \begin{macrocode}
+%
+\cs_new_protected:Npn \@@_ref_label:nn #1 #2 %label/attributes
+ {
+ \@bsphack
+ \ref_label:nn{#1}{#2}
+ \@esphack
+ }
+\cs_generate_variant:Nn \@@_ref_label:nn {en}
+% \end{macrocode}
+% This provides a condition which tests if a label/attribute combination is known

+% \section{PDF string conversion}
+%
+% This defines a command which is used to replace
+% \cs{pdfstringdef}. This is probably temporary and will be adjusted or
+% replaced if some more generic PDF string command/module exists.
+% All commands here use the \enquote{submodule} name \texttt{text}.
+% At first a hook for user additions:
+% \begin{macro}{hyp/text/pdfstring}
+% \begin{macrocode}
+\hook_new:n {hyp/text/pdfstring}
+% \end{macrocode}
+% \end{macro}
+% The first step to convert input in a PDF string is to purify it, that means
+% to remove/expand commands. As the whole process is not expandable anyway we
+% can use a protected command. The \enquote{output} is a string:
+% \begin{macro}{\@@_text_purify:nN}
+% \begin{macrocode}
+\cs_new_protected:Npn \@@_text_purify:nN #1 #2 %#1 input, #2 str command
+ {
+ \str_set:Nx #2 {\text_purify:n { #1 } }
+ }
+% \end{macrocode}
+% \end{macro}
+% The second step is to cleanup the output of the first step. This is a dummy
+% currently. The argument should be a string variable.
+% \begin{macro}{\@@_text_cleanup:N}
+% \begin{macrocode}
+\cs_new_protected:Npn \@@_text_cleanup:N #1
+ {
+
+ }
+% \end{macrocode}
+% \end{macro}
+% The last step converts the string to a PDF encoding. As we have at least two
+% targets (hex and literal) there is an argument. The conversion assumes
+% utf8 input, it is based on cs{pdf_string_from_unicode:nnN} in l3pdftools.
+%
+% \#2 is str variable,
+% \#1 should be one of
+%
+% \begin{tabular}{ll}
+% utf8/string & \texttt{(lit)} (utf8/string)\\
+% utf8/string-raw & \texttt{lit} (utf8/string)\\
+% utf8/URI & \texttt{(percent encoded url)}\\
+% utf8/URI-raw & \texttt{percent encoded url}\\
+% utf16/hex & \texttt{} (utf16/hex)\\
+% utf16/hex-raw & \texttt{HEX} (utf16/hex)\\
+% utf16/string & \texttt{(lit)} (utf16/string)\\
+% utf16/string-raw & \texttt{lit} (utf16/string)

+% \end{macro}
+% This command combines everything.
+% |#1|=input, |#2|= handler shortcut |#3|= output str variable
+% The commands uses a group to locally set \cs{Hy@pdfstringtrue}
+% so that \cs{texorpdfstring} works and other local settings can be done.

+%
+% \section{Pagelabels}
+% Page labels are representations of the page numbers in the PDF viewer. If the hyperref
+% options |pdfpagelabels| is true (the default) roman numbers are e.g. shown as
+% \enquote{ii (2/58)}. To do this the page ranges must be collected, if possible a prefix
+% and the numbering of the counter must be identified and then written
+% to the catalog.
+%
+% The current implementation in hyperref/hyperref drivers:
+% \begin{description}
+% \item[xetex:] hxetex.def, line 80-110\\
+% |\HyPL@StorePageLabel| writes to the aux-file
+% at begin document (after reading the aux)
+% |\HyPL@SetPageLabels| is called (defined in hyperref.sty after the driver
+% loading)
+% which calls |\Hy@PutCatalog{/PageLabels<>}|
+% \item[dvips:] identical to xetex, line 60 to 90 in pdfmark.def
+% \item[dvipdfm:] identical to xetex
+% \item[pdftex:] |\HyPL@StorePageLabel| stores in |\HyPL@Labels| in the first compilation
+% In |\AtVeryEndDocument| |\HyPL@SetPageLabels| is called.
+% \item[luatex] identical to pdftex
+% \end{description}
+%
+% The code in \pkg{hyperref} inspects |\thepage| and tries to figure out
+% the numbering system and the prefix. E.g. A-\arabic{page} is correctly split.
+% If the counter can not be identified \pkg{hyperref} generates only /P entries with the
+% whole content.
+%
+% The new implementation makes use of the pdf management: The relevant entry in the
+% catalog is continuously updated and pushed out at the end of the document.
+% This works (hopefully \ldots) with all drivers.
+%
+% We do not try to avoid the (in hyperref's wording)
+% \enquote{useless} pagelabel entry
+% |/PageLabels <>]>>|
+% (but it would be possible), we also don't test for empty |\thepage|,
+% \pkg{hyperref} seems to handle this fine and the pdf is valid.
+%
+% The code has to define |\Hy@PutCatalog| as we can't yet
+% change code in hyperref. The switch for draftmode has been removed.
+%
+% \begin{macro}
+% {
+% \@@_PageLabels_gpush:,
+% \Hy@PutCatalog,
+% \HyPL@StorePageLabel
+% }
+% \begin{macrocode}
+\cs_new_protected:Npn\@@_PageLabels_gpush:

+ {
+ \tl_gput_right:Nx \HyPL@Labels { \the\Hy@abspage<<#1>> }
+ \@@_PageLabels_gpush:
+ }
+ }
+% \end{macrocode}
+% \end{macro}
+% \section {Core Hyperref Commands}
+% Every hyperref has to define eight core command:
+% \begin{verbatim}
+% \hyper@anchor
+% \hyper@anchorstart
+% \hyper@anchorend
+% \hyper@link %GoTo
+% \hyper@linkstart %GoTo
+% \hyper@linkend %GoTo
+% \hyper@linkfile %GoToR
+% \hyper@linkurl %URI
+% \end{verbatim}
+%
+% This driver defines for consistency also
+% |\hyper@linklaunch| for Launch and |\hyper@linknamed| for Named.
+%
+% \subsection{ Anchors / destinations}
+% The first three commands are needed for \enquote{anchors}. At first
+% the internal commands to create a destination. It uses
+% |\Hy@WrapperDef| to make it babel safe, it is not clear if this is
+% still needed, but we leave if for now.
+% \begin{function} { \@@_destination:nn }
+% \begin{syntax}
+% \cs{@@_destination:nn} \Arg{destination name} \Arg{location}
+% \end{syntax}
+% The \meta{destination name} is encoded with the method stored in
+% in \cs{l_@@_text_enc_dest_tl}. The location should be one of
+% |fit|, |fith|, |fitv|, |fitbv|, |fitbh|, |fitr|, |xyz|, |fitrbx|.
+% The last will make use of \cs{l_@@_dest_box}
+% \end{function}
+% \begin{macro}{ \@@_destination:nn }
+% \begin{macrocode}
+\Hy@WrapperDef \@@_destination:nn #1 #2
+ {
+ \mode_if_horizontal:T { \@savsf\spacefactor }
+ \Hy@SaveLastskip %defined in hyperref
+ \Hy@VerboseAnchor{#1} %defined in hyperref, for debugging
+ \@@_text_pdfstring:xoN
+ { \HyperDestNameFilter{#1} }
+ { \l_@@_text_enc_dest_tl }
+ \l_@@_tmpa_tl
+ \str_if_eq:nnTF {#2} {fitrbox}
+ {
+ \exp_args:NV
+ \pdf_destination:nnnn \l_@@_tmpa_tl
+ { \box_wd:N \l_@@_dest_box }
+ { \box_ht:N \l_@@_dest_box }
+ { \box_dp:N \l_@@_dest_box }
+ }
+ {
+ \exp_args:NV
+ \pdf_destination:nf
+ { \l_@@_tmpa_tl }
+ { #2 }
+ }
+ \Hy@RestoreLastskip %defined in hyperref
+ \mode_if_horizontal:T { \spacefactor\@savsf }
+ }
+% \end{macrocode}
+% \end{macro}
+% This are the three destinations commands. They are modelled along the
+% xetex version. It is not quite clear if really all three
+% are needed for the backends supported by this driver, but changing the hyperref
+% code would be difficult.
+% \begin{macro}
+% {
+% \hyper@anchor,
+% \hyper@anchorstart,
+% \hyper@anchorend
+% }
+% \begin{macrocode}
+\cs_new_protected:Npn \hyper@anchor #1
+ {
+ \exp_args:NnV

+\cs_new_protected:Npn \hyper@anchorstart #1
+ {
+ \Hy@activeanchortrue
+ \exp_args:NnV
+ \@@_destination:nn {#1} \l_@@_dest_pdfview_tl
+ }
+
+\cs_new_protected:Npn \hyper@anchorend
+ {
+ \Hy@activeanchorfalse
+ }
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{GoTo Links}
+% The next three commands are for links inside the document,
+% to destinations (GoTo links).
+% The definition in \pkg{hyperref} have a first argument which
+% can be used to pass a semantical context. Currently this argument is
+% only used for \cs{cite} and only to change the color. The new
+% implementation uses it for a real hook.
+%
+% At first the internal link commands:
+% \begin{macrocode}
+\cs_new_protected:Npn \@@_link_goto_begin:nw #1
+ {
+ \mode_leave_vertical:
+ \protected@edef \l_@@_dest_name_tmpa_tl { #1 }
+ \tl_if_empty:NTF \l_@@_dest_name_tmpa_tl
+ {
+ \msg_warning:nnx
+ { hyp }
+ { empty-destination-name }
+ { \c_@@_dest_undefined_tl }
+ \tl_set_eq:NN \l_@@_dest_name_tmpa_tl \c_@@_dest_undefined_tl
+ }
+ {
+ \@@_text_pdfstring:xoN
+ { \exp_args:No \HyperDestNameFilter { \l_@@_dest_name_tmpa_tl } }
+ { \l_@@_text_enc_dest_tl }
+ \l_@@_dest_name_tmpa_tl
+ }
+ \exp_args:No
+ \pdfannot_link_goto_begin:nw { \l_@@_dest_name_tmpa_tl }
+ }
+
+\cs_new_protected:Npn \@@_link_goto_end:
+ {
+ \pdfannot_link_goto_end:
+ }
+% \end{macrocode}
+%
+% Now the three hyperref commands.
+% The splitted commands \cs{hyper@linkstart} and \cs{hyper@linkend} are used for
+% footnotemarks, toc and natbib-cites.
+% \begin{function}{\hyper@link}
+% \begin{syntax}
+% \cs{hyper@link}\Arg{context}\Arg{destination name}\Arg{link text}
+% \end{syntax}
+% This creates a complete GoTo link around the \meta{link text}
+% pointing to \meta{destination name}.
+% The hook |hyp/link/|\meta{context} is executed at the begin if it exists.
+%
+% The only \meta{context} for which a hook is predefined is |cite|.
+% Packages which want to use another \meta{context} should initialize the hook like
+% this:
+% \begin{verbatim}
+% \IfHookExistsTF{hyp/link/context}{}
+% {\NewHook{hyp/link/context}}
+% \end{verbatim}
+%
+% The hook code is executed in a group but before all the pdfannot hooks.
+% \end{function}
+% \begin{function}{\hyper@linkstart,\hyper@linkend}
+% \begin{syntax}
+% \cs{hyper@linkstart}\Arg{context}\Arg{destination name}\\
+% \cs{hyper@linkend}
+% \end{syntax}
+% This creates the start and end commands for a GoTo link around the text
+% between both pointing to \meta{destination name}.
+% The hook |hyp/link/|\meta{context} is executed at the begin if it exists
+% as with \cs{hyper@link}
+%
+% The commands open and close a group, so should be placed carefully. .
+% \end{function}
+
+% \pkg{hyperref} adds a group with \cs{Hy@colorlink}, we move this outside the link
+% so that it groups the context hook too.
+% \begin{macrocode}
+
+\cs_new_protected:Npn \hyper@link #1 #2 #3 %#1 context, #2=destination name, #3 content
+ {
+ \bool_if:NTF \l_@@_annot_GoTo_bool
+ {
+ \Hy@VerboseLinkStart{#1}{#2}
+ \group_begin:
+ \hook_use:n {hyp/link/#1}
+ \@@_link_goto_begin:nw {#2}#3\Hy@xspace@end
+ \__hyp_link_goto_end:
+ \group_end:
+ \Hy@VerboseLinkStop
+ }{#3}
+ }
+
+\cs_new_protected:Npn \hyper@linkstart #1 #2 %#1 context, #2=destination name
+ {
+ \bool_if:NT \l_@@_annot_GoTo_bool
+ {
+ \Hy@VerboseLinkStart{#1}{#2}% only for debug
+ \group_begin:
+ \hook_use:n {hyp/link/#1}
+ \@@_link_goto_begin:nw {#2}
+ }
+ }
+
+\cs_new_protected:Npn \hyper@linkend
+ {
+ \bool_if:NT \l_@@_annot_GoTo_bool
+ {
+ \@@_link_goto_end:
+ \group_end:
+ \Hy@VerboseLinkStop
+ }
+ }
+% \end{macrocode}
+%
+% \subsection{URI links}
+% We define a dictionary for the action dictionary. For now it is public.
+% \begin{macrocode}

+ }
+ }
+% \end{macrocode}
+% Transition settings are used by (some) pdf viewers when presenting a
+% pdf in full screen mode. They are added to the page settings and describe the
+% transition from the previous page to current page. Transition setting can be
+% set in the preamble for all pages or in the document for the current and the
+% following pages. Due to the asynchronous page breaking one has to be careful
+% to set it on the right page, e.g. only after a |\newpage|.
+% The generic driver uses a different syntax than the other hyperref drivers:
+% various transition options can be set by a keyval syntax in the value of
+% |pdfpagetransition|. A typical setting looks e.g. like this\\
+% |\hypersetup{pdfpagetransition={style=Fly,duration=2,direction=90,opaque=false}}|
+%
+% The keys allowed in the argument of |pdfpagetransition| are
+% \begin{tabular}{l>{\raggedright\arraybackslash}p{6cm}}
+% style & one of Split, Blinds, Box, Wipe, Dissolve, Glitter, R, Fly, Push, Cover, Uncover, Fade\\
+% duration & a number, describes the duration of the transition\\
+% direction& \begin{tabular}[t]{l}
+% H~(horizontal,~only~Split,~Blinds)\\
+% V~(vertical,~only~Split,~Blinds)\\
+% 0~(left~to~right,~only~Wipe,~Glitter,~Fly,~Cover,~Uncover,~Push)\\
+% 90~(bottom~to~top,~only~Wipe)\\
+% 180~(right~to~left,~only~Wipe)\\
+% 270~(top~to~bottom,~only~Wipe,~Glitter,~Fly,~Cover,~Uncover,~Push)\\
+% 315~(top~left~to~bottom,~only~Glitter)\\
+% None~(only~Fly)
+% \end{tabular}\\
+% motion & one of I, O, only relevant for Split, Box and Fly\\

+% \subsubsection{Add the \enquote{shipout} hooks}
+% Now we add to the shipout hooks the relevant token lists.
+% We also push the page resources in shipout/firstpage (AtBeginDvi)
+% as the backend code sets color stack there. The xetex driver needs a rule here.
+% If it clashes on the first page, we will need a test ...

+% \subsection{ The /Pages dictionary (pdfpagesattr) }
+% \begin{NOTE}{UF}
+% path: Pages
+% pdfpagesattr is a single token register which is used at the end of the compilation.
+% dvips syntax: \verb+\special{ps: [/ABC /CDE /EFG /FGH /Rotate 90 /PAGES pdfmark}+
+% dvipdfmx syntax: \verb+\special{pdf:put @pages <>}+
+% both remove duplicate entries automatically, so there is no need to be careful.
+% \end{NOTE}
+% \begin{macro}{\@@_backend_Pages_primitive:n}
+% This is the primitive command to add something to the /Pages dictionary.
+% It works differently for the backends: pdftex and luatex overwrite existing
+% content, dvips and dvipdfmx are additive. luatex sets it in lua.
+% The higher level code has to take this into account.

+% \subsection{\enquote{Page} and \enquote{ThisPage} attributes (pdfpageattr)}
+% \begin{NOTE}{UF}
+% path: Page
+% !!!!!!!!!!!!!!!!!!!!!!
+% This part of the code depends on zref/xref as it sets labels.
+% It also depends on code in l3pdfmanagement as the code uses the Core-dictionaries
+% !!!!!!!!!!!!!!!!!!!!!!
+%
+% The engines differ a lot here: pdflatex and lualatex uses a register while with
+% dvips/dvipdfmx a one-shot-special is used. So for pdflatex and lualatex code
+% to assemble the content of the register is needed. Specials are used at shipout,
+% the registers is set directly. With lualatex one can use
+% \cs{latelua} to delay the setting, with pdflatex one has to use a shipout hook.
+% To get the code on the correct page one has to use the aux with pdflatex.
+% In sum this means that quite a lot backend commands are needed to handle
+% this differences. Simply variants of \cs{pdfpageattr} are not enough ...%
+% dvips syntax: \special{ps: [{ThisPage}<> /PUT pdfmark}%
+% There seem to be an in-built management code: multiple uses don't lead to
+% multiple entries (/Rotate is special: there is always a /Rotate 0 in the dict,
+% but seems not to do harm).
+% dvipdfmx syntax: \special{pdf: put @thispage << /Rotate 90 >>},
+% like dvips the backend has an in-built management code.
+% Both change only the current page, so to get the pdftex behavior (which sets
+% also the following pages) one need to repeat it on every shipout.
+% \end{NOTE}

+% \cs{@@_backend_Page_gremove:n} allows to remove a value.
+% \cs{@@_backend_ThisPage_gput:nn} adds a value to the current page.
+% \cs{@@_backend_ThisPage_gpush:n} merges the default and the current page values

+% \begin{documentation}
+%
+% \section{\pkg{l3pdfannot} documentation}
+% This module contains a number of commands to create PDF annotations.
+% The commands are \emph{not} always simple wrappers around primitive commands.
+% To allow external packages to configure links and other annotations,
+% some of the commands have hooks and use shared attribute dictionaries.
+% For these commands the hooks and dictionaries are selected depending on the \meta{type}
+% of the annotation. Currently the module only supports some general commands
+% and link annotations. Commands for other annotations like widgets will be added
+% later.
+%
+% \subsection{General annotation commands}
+%
+% \begin{function}[added = 2019-09-05, updated = 2020-04-14]
+% { \pdfannot_box:nnnn }
+% \begin{syntax}
+% \cs{pdfannot_box:nnnn} \Arg{width} \Arg{height} \Arg{depth} \Arg{annot spec}
+% \end{syntax}
+% This creates an \texttt{/Type/Annot} object with the given dimensions.
+% It doesn't use hooks or dictionaries.
+% \end{function}
+% \begin{function}[added = 2020-03-30]
+% { \pdfannot_box:nnnnn }
+% \begin{syntax}
+% \cs{pdfannot_box:nnnnn} \Arg{type} \Arg{width} \Arg{height} \Arg{depth} \Arg{annot spec}
+% \end{syntax}
+% This creates an \texttt{/Type/Annot} object with the given dimensions.
+% \meta{type} should be currently one of |link/URI|, |link/GoToR|,
+% |link/Launch|, |link/GoTo| or |link/Named| or
+% |widget|, it will then insert the attribute dictionary of this type
+% additionally to the manually given \meta{annot spec}.
+% The attribute dictionaries can be filled with commands described below.
+% Hooks are not used.
+% \end{function}
+% \begin{function}[added = 2019-09-05]
+% { \pdfannot_box_ref_last: }
+% \begin{syntax}
+% \cs{pdfannot_box_ref_last:}
+% \end{syntax}
+% This retrieves the object reference of the last box annotation created.
+% \end{function}
+% \subsection{Link annotations}
+% Link annotations are special cases of annotations. In the PDF they are identified
+% by an |/Subtype/Link| entry in the dictionary.
+% Link annotations are quite important as many documents contain links,
+% both internal and external. They need a set of special commands for two reasons:
+%
+% At first the content of links are not only boxes. Links can contain line
+% and page breaks (this is normally implemented by the primitive command by
+% creating a set of annotations).
+%
+% At second link annotations are objects that need some
+% \enquote{management} as more than one
+% package wants to configure their look and behaviour.
+% For example \pkg{hyperref}, \pkg{ocgx2} and the code for tagged PDF (currently
+% in \pkg{tagpdf}) all want to add keys and values to the dictionaries of
+% link annotation and code around links.
+% So commands to create link annotations should offer suitable hooks.
+% There are three standard places in a link where such hooks are needed:
+% At the begin (for example for a structure command or color),
+% in the \emph{attr spec} dictionary of the link (for example for the border), and
+% at the end of the link (to close a structure or the color group).
+% For the begin and end hooks of the LaTeX hook management are predefined and used.
+% To add and remove values from the \emph{attr spec} dictionary special
+% commands described below are provided. The link commands switch to horizontal mode
+% as the commands of pdftex and luatex can't be used in vertical mode.
+%
+% \begin{variable}{\c_pdfannot_link_types_seq}
+% There are currently five link types, \texttt{URI}, \texttt{GoToR},
+% \texttt{Launch}, \texttt{GoTo} or \texttt{Named}, and there are store in this
+% constant.
+% \end{variable}
+% \begin{variable}
+% {
+% pdfannot/link/TYPE/before,
+% pdfannot/link/TYPE/begin,
+% pdfannot/link/TYPE/end,
+% pdfannot/link/TYPE/after
+% }
+% These are the hooks used by the following commands. TYPE can be one of
+% \texttt{URI}, \texttt{GoToR},
+% \texttt{Launch}, \texttt{GoTo} or \texttt{Named}
+% \end{variable}
+% \begin{variable}
+% {
+% link/TYPE
+% }
+% These is the name of the dictionary used by the following commands. TYPE can be one of
+% \texttt{URI}, \texttt{GoToR},
+% \texttt{Launch}, \texttt{GoTo} or \texttt{Named}. The dictionary can be changed
+% by the commands \cs{pdfannot_dict_put:nnn} and friends described below.
+% \end{variable}
+% \begin{function}[added = 2020-03-12, updated = 2020-12-06]{ \pdfannot_link:nnn }
+% \begin{syntax}
+% \cs{pdfannot_link:nnn} \Arg{type} \Arg{user action spec} \Arg{link text}
+% \end{syntax}
+% This creates a link around the \meta{link text} with the specified
+% \meta{user action spec}\footnote{The wording follows the pdftex documentation}.
+% \texttt{/Subtype/Link} is added automatically.
+% \meta{type} should be one of \texttt{URI}, \texttt{GoToR},
+% \texttt{Launch}, \texttt{GoTo} or \texttt{Named}. The |GoTo| variant does
+% \emph{not} complain if the destination name is not known like
+% \cs{pdfannot_link_goto_begin:nw}.
+% The attributes stored in the local dictionary
+% \texttt{link/}\meta{type} are inserted as
+% \emph{attr spec} and the code in the begin and end hook
+% \texttt{pdfannot/link/\meta{type}/before}
+% and \texttt{pdfannot/link/\meta{type}/after}
+% is executed before and after the link (outside the link command)
+% while \texttt{pdfannot/link/\meta{type}/begin}
+% and \texttt{pdfannot/link/\meta{type}/end} are directly around the link
+% text. None of the hooks introduce a group.
+% \meta{type} should normally be identical to the value of the |/S| key
+% in the action dictionary.
+% As example
+% \begin{verbatim}
+% \pdfannot_dict_put:nnn
+% {link/URI} { C } {[1~0~0]} %red border
+% \pdfannot_link:nnn { URI }
+% {
+% /A
+% <<
+% /Type/Action
+% /S/URI
+% /URI(https://www.latex-project.org)
+% >>
+% }
+% { link text }
+% \end{verbatim}
+%
+%
+% \end{function}
+% \begin{function}[updated = 2020-12-06]{ \pdfannot_link_begin:nnw, \pdfannot_link_end:n }
+% \begin{syntax}
+% \cs{pdfannot_link_begin:nnw} \Arg{type} \Arg{user action spec} \meta{content}
+% \cs{pdfannot_link_end:n} \Arg{type}
+% \end{syntax}
+% This creates a link around the \meta{content} with the specified
+% \meta{user action spec} (e.g. an /A dictionary with an URI) or
+% \meta{destination} (a name as defined with the
+% first argument of \cs{pdf_destination:nn}).
+% \texttt{/Subtype/Link} is added automatically.
+% In contrast to \cs{pdfannot_link:nnn} this function
+% does not absorb the argument when finding the \meta{content}, and so can
+% be used in circumstances where the \meta{content} may not be a simple
+% argument. But beside this, it works similar and use the same hooks.
+% As example
+% \begin{verbatim}
+% \pdfannot_link_begin:nnw { URI }
+% {
+% /A<<
+% /Type/Action
+% /S/URI
+% /URI(https://www.latex-project.org)
+% >>
+% }
+% link text
+% \pdfannot_link_end:n { URI }
+% \end{verbatim}
+% \end{function}
+% \begin{function}[updated = 2020-12-06]{ \pdfannot_link_goto_begin:nw, \pdfannot_link_goto_end: }
+% \begin{syntax}
+% \cs{pdfannot_link_goto_begin:nw} \Arg{destination} \meta{content}
+% \cs{pdfannot_link_goto_end:}
+% \end{syntax}
+% This is a special, shorter version for links to internal destinations. It always
+% uses the hooks and dictionary of the |GoTo| link type. \meta{destination} is a
+% destination name. In difference to |\pdfannot_link:nnn { GoTo }| it will complain if
+% \meta{destination} is an unknown destination and give the message
+%
+% |name{ZZZZ} has been referenced but does not exist, replaced by a fixed one|
+%
+% \end{function}
+% \begin{function}[added = 2021-02-14]{ \pdfannot_link_ref_last: }
+% This retrieves the object reference a link created previously with the commands
+% above. This doesn't work currently with xelatex but a feature request has
+% been made. see https://tug.org/pipermail/dvipdfmx/2020-December/000134.html
+% \end{function}
+% \begin{function}[added = 2021-02-14]{ \pdfannot_ref_last: }
+% This retrieves the object reference a previously annotation
+% created either with a link or a general box command. When the last was a link
+% it won't work with xelatex.
+% see https://tug.org/pipermail/dvipdfmx/2020-December/000134.html
+% \end{function}
+% \begin{NOTE}{UF}
+% only annot link or also annot?
+% \end{NOTE}
+% \begin{function}[added = 2020-03-12]{ \pdfannot_link_margin:n }
+% \begin{syntax}
+% \cs{pdfannot_link_margin:n} \Arg{dimen}
+% \end{syntax}
+% This sets the dimension of the link margin.
+% \end{function}
+% \begin{function}[added = 2020-12-04]{ \pdfannot_dict_put:nnn }
+% \begin{syntax}
+% \cs{pdfannot_dict_put:nnn} \Arg{dictionary name} \Arg{key} \Arg{value}
+% \end{syntax}
+% This adds (locally) a key-value to the internal annot dictionaries used
+% by the link commands above.
+% \meta{dictionary name} should be currently one of \texttt{link/URI},
+% \texttt{link/URI},\texttt{link/GoToR}, \texttt{link/Launch},
+% \texttt{link/GoTo}, \texttt{link/Named}.
+% \end{function}
+% \begin{function}[added = 2020-12-04]{ \pdfannot_dict_remove:nn }
+% \begin{syntax}
+% \cs{pdfannot_dict_remove:nn} \Arg{dictionary name} \Arg{key}
+% \end{syntax}
+% This removes a key-value from the internal annot dictionary
+% \meta{dictionary name} should be currently one of
+% \texttt{link/URI}, \texttt{link/GoToR}, \texttt{link/Launch},
+% \texttt{link/GoTo}, \texttt{link/Named}.
+% \end{function}
+% \begin{function}[added = 2020-12-04]{ \pdfannot_dict_show:n }
+% \begin{syntax}
+% \cs{pdfannot_dict_show:n} \Arg{dictionary name}
+% \end{syntax}
+% This shows the content of the internal annot dictionary.
+% \meta{dictionary name} should be currently one of \texttt{link/URI},
+% \texttt{link/URI}, \texttt{link/GoToR}, \texttt{link/Launch},
+% \texttt{link/GoTo}, \texttt{link/Named}.
+% \end{function}
+%
+% \begin{variable}[added = 2020-12-28]{\l_pdfannot_F_bitset}
+% This is a bitset variable, with the named index names suitable for the
+% /F flag in an annotation.
+% It can be used for example like this:
+% \begin{verbatim}
+% \pdfannot_dict_put:nnn {link/URI} {F}
+% { \bitset_to_arabic:N \l_pdfannot_F_bitset }
+% \bitset_set_true:Nn \l_pdfannot_F_bitset {Print}
+% \end{verbatim}
+% The known keys for the bitset are |Invisible|, |Hidden|,
+% |Print|, |NoZoom|, |NoRotate|, |NoView|, |ReadOnly|, |Locked|, |ToggleNoView|,
+% |LockedContents| which correspond to the names used in the PDF references.
+% \end{variable}

+% \subsection{Annotations, subtype Widget}\label{pdf:annot:widget}
+% Currently no code is provided here.
+% The local dictionary \texttt{l_@@/Widget} is a skeleton
+% dictionary for this subtype. It currently contains as only entry
+% the subtype setting (the /Type is added by the backend).
+% \begin{macrocode}

+ \pdfdict_put:nnn { l_@@/widget }{ Subtype }{ /Widget }
+% \end{macrocode}
+%
+% \subsection{Annotations, subtype Link}\label{sec:links}
+% The code assumes that there will be different link types
+% (currently URI, GoToR, Launch, GoTo, Named, hyperref uses the names
+% url,file,run,link,menu) and that links of the same type share
+% the \emph{attr spec} and also the same begin/end
+% code. The list of link types need to stay restricted and well documented so that
+% all packages know which types they have to handle. It is stored in a constant
+% seq.
+% \begin{NOTE}{UF}
+% Perhaps a |cite| type will be useful at some time. -- Thinking more about it,
+% a |cite| type is not sensible. hyperref supports it, but it doesn't fit in.
+% Commands like cite, gls, acro, footnote and so on should locally change
+% linkcolor and linkbordercolor.
+% Probably we will need some commands to add an attribute to all link types
+% at once.
+% hyperref commands for the various type:
+% url |\hyper@linkurl|,
+% file |\hyper@linkfile|,
+% run |\@hyper@launch run|,
+% link |\hyper@link|, |\find@pdflink|
+% menu |\Acrobatmenu|
+% \end{NOTE}

+%
+% \section{\pkg{l3pdfdict} documentation}
+% Many PDF objects are or contain dictionaries---structures
+% containing a number of \mbox{(pdf-)}name/value pairs.
+% Examples are attributes of links,
+% filespec dictionaries, xform dictionaries, the catalog, the info dictionary.
+% The commands in this module offer an number of
+% tools to handle such dictionaries. The module setups a name space for the
+% dictionary names and offers some commands to output dictionaries.
+%
+% The dictionaries work in many respects
+% like property lists with a few PDF specific changes:
+% \begin{itemize}
+% \item The keys are always converted with \cs{str_convert_pdfname:n}
+% to get a correct PDF name;
+% \item a key with a empty value can not be added, it will be ignored;
+% \item there is a dedicated function to output the property as space
+% separated list with keys with slash: \texttt{/key1 value1 /key2 value2}.
+% \end{itemize}
+% Local and global dictionaries can be created.
+%
+% \subsection{User Commands}
+% \begin{function}[updated = 2020-12-03]
+% {\pdfdict_new:n}
+% \begin{syntax}
+% \cs{pdfdict_new:n} \Arg{dictionary name}
+% \end{syntax}
+% This function create a new local or global dictionary. Which one depends on
+% \meta{dictionary name}: If it begins with the standard |g| the dictionary is global,
+% with |l| the dictionary is local, other starting chars will give an error.
+% It is recommended to begin the name in the standard expl3 naming scheme
+% with one or two underscores and a module name,
+% so |g_module_XXXX| or |g__module_XXXX|.
+% \end{function}
+%
+% \begin{function}[added = 2020-06-16,updated = 2020-12-03]
+% {\pdfdict_set_eq:nn,\pdfdict_gset_eq:nn}
+% \begin{syntax}
+% \cs{pdfdict_set_eq:nn} \Arg{local dictionary name_1} \Arg{dictionary name_2}\\
+% \cs{pdfdict_gset_eq:nn} \Arg{global dictionary name_1}\Arg{dictionary name_2}
+% \end{syntax}
+% This functions copy \meta{dictionary name_2} into
+% \meta{local/global dictionary name_1} locally or globally. If the
+% dictionary \meta{local/global dictionary name_1} doesn't exist yet, it will be created.
+% If \meta{dictionary name_2} doesn't exist yet, an error will be raised.
+% \end{function}
+%
+% \begin{function}[added = 2020-04-06]
+% {\pdfdict_put:nnn, \pdfdict_gput:nnn}
+% \begin{syntax}
+% \cs{pdfdict_put:nnn} \Arg{local dictionary} \Arg{name} \Arg{value} \\
+% \cs{pdfdict_gput:nnn} \Arg{global dictionary} \Arg{name} \Arg{value}
+% \end{syntax}
+% This function puts key \meta{name} and value \meta{value} locally or globally in the
+% \meta{dictionary} created with \cs{pdfdict_new:n}.
+% \Arg{name} should be a PDF Name without the starting slash. It will be stored
+% with \cs{str_convert_pdfname:n}, so will be automatically correctly escaped in case
+% it contains slashes, spaces or other chars not allowed in a PDF name.
+% \meta{value} should be a valid PDF value for this name in the
+% target dictionary. The value is \emph{neither} converted \emph{nor} escaped automatically.
+% If the value is blank nothing is added to the dictionary.
+%
+% When adding a value keep in mind that the expansion behaviour
+% of the backends differ. Some backends expand a
+% value always fully when writing to the PDF, with other backends commands
+% could end as strings in the PDF. This makes controlling the
+% expansion quite tricky. It is better to not rely on
+% \meta{value} to be expanded nor not expanded by the backend commands.
+% \end{function}
+%
+% \begin{function}[EXP,added = 2020-12-04]
+% { \pdfdict_item:nn, \pdfdict_item:ne }
+% \begin{syntax}
+% \cs{pdfdict_item:nn} \Arg{key} \Arg{value}
+% \end{syntax}
+% A simple command to output key-value as |/key value|. This is
+% needed to output dictionaries in mapping commands. The command doesn't
+% do any escaping, it expects that the name has been escaped when the value
+% has been stored into the dictionary.
+% If the value is blank nothing is output.
+% The command is expandable if the content is it.
+% \end{function}
+%
+% \begin{function}[EXP,updated = 2020-12-03]
+% { \pdfdict_use:n }
+% \begin{syntax}
+% \cs{pdfdict_use:n} \Arg{dictionary}
+% \end{syntax}
+% This outputs the property list of the dictionary as a list of
+% |/key value| pairs.
+% This can be used e.g. when writing a dictionary object with
+% \cs{pdf_object_write:nx}
+% \end{function}
+%
+% \begin{function}[updated = 2020-12-03]
+% {\pdfdict_show:n }
+% \begin{syntax}
+% \cs{pdfdict_show:n} \Arg{dictionary}
+% \end{syntax}
+% This shows the content of \meta{dictionary} in the log and on the terminal.
+% \end{function}
+%\begin{function}[EXP, pTF,updated = 2020-12-03]
+% { \pdfdict_if_exist:n }
+% \begin{syntax}
+% \cs{pdfdict_if_exist:n} \Arg{dictionary}
+% \end{syntax}
+% This tests if the dictionary exists.
+% \end{function}
+% \begin{function}[EXP, pTF,updated = 2020-12-03]
+% { \pdfdict_if_empty:n }
+% \begin{syntax}
+% \cs{pdfdict_if_empty:n} \Arg{dictionary}
+% \end{syntax}
+% This tests if the dictionary is empty. The result is false if the
+% dictionary doesn't exist.
+% \end{function}
+% \begin{function}[added = 2020-07-06]
+% {\pdfdict_get:nnN }
+% \begin{syntax}
+% \cs{pdfdict_get:nnN} \Arg{dictionary} \Arg{name} \meta{tl var}
+% \end{syntax}
+% Recovers the \meta{value} stored by \cs{pdfdict_put:nnn} or
+% \cs{pdfdict_gput:nnn}
+% for \meta{name} and places this in the \meta{token list
+% variable}. If \meta{name} is not found
+% then the \meta{token list variable} is set
+% to the special marker \cs{q_no_value}. \meta{name} is first converted
+% with \cs{str_convert_pdfname:n}. The \meta{token list
+% variable} is set within the current \TeX{} group.
+% \end{function}
+%
+% \begin{function}[updated = 2020-12-03]
+% {
+% \pdfdict_remove:nn, \pdfdict_gremove:nn
+% }
+% \begin{syntax}
+% \cs{pdfdict_remove:nn} \Arg{local dictionary} \Arg{name}\\
+% \cs{pdfdict_gremove:nn} \Arg{global dictionary} \Arg{name}
+% \end{syntax}
+% Removes \meta{name} and its associated \meta{value} from
+% the \Arg{dictionary}
+% The removal is local from local dictionaries
+% and global from global dictionaries.
+% If \meta{name} is not found no change occurs,
+% \emph{i.e}~there is no need to test for the existence of a name before
+% trying to remove it. \meta{name} is first converted
+% with \cs{str_convert_pdfname:n}.

+% \subsection{Introduction}
+% \subsubsection{Background}
+% External files can be referenced from a PDF in three ways:
+% \begin{enumerate}
+% \item through an annotation of type Link,
+% \item by referencing a local file in the file system,
+% \item by embedding the file directly into the PDF
+% \end{enumerate}
+% Case 1 (Links) are created with the \cs{pdfannot} commands.
+% This module handles the two other cases. Actually from the view
+% of the PDF format they are quite similar: Case 2 is case 3 without the stream
+% object and without the /EF entry in the /FileSpec dictionary (this points to the
+% stream object of the file). Not embedding the file makes the PDF smaller. But it is
+% also less portable: the files can only be found if they are in the right location
+% relative to the PDF. The normal case is to embed the file.
+%
+% The tasks to embed and reference such a file are
+% \begin{enumerate}
+% \item Embed the file in a stream.
+% \item Create a FileSpec dictionary which references the stream object in the /EF
+% dictionary:
+% \begin{verbatim}
+% <<
+% /Type /Filespec
+% /F (l3pdffile.dtx)
+% /UF (l3pdffile.dtx)
+% /AFRelationship /Source
+% /EF <> %case 3, embedded file
+% >>
+% \end{verbatim}
+% The file names in the /UF and /F value don't need to be identical to the
+% name of file on the disc. It is quite possible to embed a \texttt{zzz.tex}
+% and name it \texttt{blub.tex}. The second name is then what the user will see
+% in the attachment list or in the properties of an annotation.
+%
+%\item Reference the FileSpec dictionary so that the user can access the file.
+% This can be done in various way:
+% \begin{enumerate}
+% \item With an annotation (/Subtype/FileAttachment). This is done by
+% \pkg{attachfile}, \pkg{attachfile2} and \pkg{intopdf}.
+% Typical entries of such an annotation are:
+%
+% \medskip
+% \begin{tabular}{lll}
+% key & value type & notes\\\hline
+% /FS & object reference &(FileSpec dictionary)\\
+% /Name & name & /Graph, /PushPin, /Paperclip, /Tag\\
+% /Contents & text string & optional but recommended\\
+% /F & integer & Flags\\
+% /AP & dictionary & Appearance (required if rectangle >0) \\
+% /AS & name\\
+% \end{tabular}
+%
+% The |/AP| takes precedence over Border and similar keys.
+% \item Through an entry in the |/EmbeddedFiles| name tree.
+% This is what \pkg{embedfiles} does.
+% \begin{verbatim}
+% 20 0 obj %Document Name tree
+% <>
+% endobj
+% 21 0 obj %Embedded Files Name dictionary
+% <>
+% endobj
+% \end{verbatim}
+% The strings (keys) in the |/Names| dictionary must be sorted lexically.
+% But they don't have to be the file name or anything related to
+% the file name. The resource management code uses l3emb0001, l3emb0002~\ldots,
+% which allows up to 9999 files.
+% The key can be needed to identify the start file in a collection,
+% so their relation to the files are stored in a property list.
+%
+% \item Through the |/AF| key in various objects (pdf 2.0).
+% The value is normally an array of object
+% references, but it can also be a name which is mapped to an array in /Properties:
+% \begin{verbatim}
+% /AF /NamedAF BDC
+% /Properties <>
+% }
+% {example-image.eps}
+% }
+% \tl_set:Nx \l_my_fileobj_tl {\pdf_object_ref_last:}
+% \end{verbatim}
+%
+% \begin{itemize}
+% \item The |/Params| dictionary is not always required, but the commands of
+% these module will prefill them as shown in the examples. A |/CreationDate| entry
+% has to be added explicitly as there is no sensible way
+% to retrieve this automatically.
+% \item The mimetype (in the |/Subtype|) should be properly escaped.
+% This module contains a property list with maps a number of file extensions
+% to mimetypes and the commands try to detect and fill the mimetype automatically.
+% \item The dictionary can contain additional keys (|/Filter|, |/DecodeParms|),
+% see the pdf reference.
+% \end{itemize}
+%
+% \subsubsection{Task 2: Creating the \texttt{/FileSpec} dictionary}
+% The |/FileSpec| dictionary is a simple dictionary object, and can also
+% be created in various ways. If it refers to an embedded file it should
+% reference it in the |/EF| key.
+%
+% \subsubsection{Task 3: Referencing the \texttt{/FileSpec} dictionary}
+%
+% Using the dictionary reference in annotations and |/AF| keys is unproblematic.
+%
+% \potentialclash
+% But to add it to the |/EmbeddedFiles| name tree so that it appears in the
+% attachment panel requires special care:
+% This name tree is a global resource and uncoordinated access can lead to
+% clashes and files that are not visible or inaccessible.
+% The access here is managed by the \pkg{l3pdfmanagement} module:\\[\smallskipamount]%
+% |\pdfmanagement_add:nnx{Catalog/Names}{EmbeddedFiles}{|\meta{objref}|}|
+%
+% \subsection{Commands and tools of these module}
+% \begin{function}{file, file/Params, file/streamParams,file/FileSpec}
+% The module predefines and uses a number of local dictionaries for the
+% components of the stream and the |/FileSpec| object. These dictionaries are
+% then used by the \cs{pdffile_embed_XX}.
+% The content of these dictionaries can be changed by users with the commands
+% from the \pkg{l3pdfdict} module, but it should be done only locally
+% to avoid side effects on uses by other packages/commands.
+
+% The preset values are of these dictionaries are shown in table~\ref{tab:filedict}.
+% \end{function}
+% \begin{table}
+% \caption{Preset values in the file dictionaries\label{tab:filedict}}
+% \begin{tabular}{lll}
+% dictionary & key & value \\\hline
+% l\_pdffile & Type & /EmbeddedFile\\
+% l\_pdffile/Params& Size & |\file_size:n{\l_pdffile_source_name_str}|\\
+% l\_pdffile/Params& ModDate & |(\file_timestamp:n {\l_pdffile_source_name_str})|\\
+% l\_pdffile/Params& CheckSum & |(\file_mdfive_hash:n{\l_pdffile_source_name_str})|\\
+% l\_pdffile/streamParams& & a /ModDate entry with year/month/date (used with \cs{pdffile_embed_stream:nnn})\\
+% l\_pdffile/FileSpec & Type & /FileSpec\\
+% l\_pdffile/FileSpec & AFRelationship &Unspecified
+% \end{tabular}
+% \end{table}
+% \begin{function}{\pdffile_embed_file:nnn}
+% \begin{syntax}
+% \cs{pdffile_embed_file:nnn} \Arg{source filename} \Arg{target filename} \Arg{object name }
+% \end{syntax}
+% This commands embeds the file \meta{source filename} in the PDF,
+% and creates a |/FileSpec| dictionary object named \meta{object name}.
+% The object name must be unique.
+% The command uses the content of the local
+% dictionaries |l_pdffile|, |l_pdffile/Params| and |l_pdffile/FileSpec|
+% to setup the dictionary entries of the stream object and the
+% |/FileSpec| dictionary. The |/F| and |/UF| entry are filled
+% with \meta{target filename}.
+%
+% It is an error if both \meta{target filename} and \meta{source filename}
+% are empty.
+%
+% If \meta{target filename} is empty \meta{source filename} is used instead.
+%
+% If \meta{source filename} is empty, only a |/FileSpec| dictionary is
+% created.
+%
+% If the |l_pdffile| dictionary doesn't contain a
+% Subtype entry with the mimetype, the command tries to guess it
+% from the file extension of \meta{source filename}. Unknown file extensions can be
+% added (or known extension be changed) by adding to or changing the value in
+% the property \cs{g_pdffile_mimetypes_prop}, see below.
+%
+% When using \texttt{dvips} and \texttt{pstopdf} the actual embedding is
+% done by \texttt{pstopdf}. \texttt{pstopdf} will embed files
+% only if used with the option \texttt{-dNOSAFER} and will not be able
+% to use files which are found with \texttt{kpathsea}.
+%
+% \meta{target filename} doesn't need to be a file name with an extension,
+% but it is recommended as security settings in the pdf
+% viewer can restrict access to known file types.
+% \end{function}
+%
+% \begin{NOTE}{UF}
+% we should perhaps also consider the chunk method see pdfbase and
+% https://chat.stackexchange.com/transcript/message/54181193#54181193
+% \end{NOTE}
+%
+% \begin{function}{\pdffile_embed_stream:nnn}
+% \begin{syntax}
+% \cs{pdffile_embed_stream:nnn} \Arg{content} \Arg{target filename} \Arg{object name }
+% \end{syntax}
+% This commands embeds the \meta{content} in the PDF in a stream objects and
+% creates a |/FileSpec| dictionary object named \meta{object name}.
+% \meta{content} is wrapped in a \cs{exp_not:n}.
+% The object name must be unique. The command uses the content of the local
+% dictionaries |l_pdffile|, |l_pdffile/streamParams| and |l_pdffile/FileSpec|
+% to setup the dictionary entries of the stream object and the /FileSpec dictionary.
+% The /F and /UF entry are filled with \meta{target filename}.
+% If \meta{target filename} is empty the fix name \texttt{stream.txt}
+% is used instead.
+%
+% If the |l_pdffile| dictionary doesn't contain a
+% Subtype entry with the mimetype, the command tries to guess it
+% from the file extension of \meta{target filename}.
+%
+% \meta{target filename} doesn't need to be a file name with an extension,
+% but it is recommended as security settings in the pdf
+% viewer can restrict access to known file types.
+%
+% The stream should not be too long, at least PS imposes a size limit for strings.
+% \end{function}
+%
+% \begin{variable}{\g_pdffile_mimetypes_prop}
+% This property contains a list of extensions and their mimetypes.
+% Values can be added or changed with the standard commands:
+%
+% |\prop_gput:Nnn \g_pdffile_mimetypes_prop {.abc}{text/plain}|
+%
+% The extension should start with a period, the mimetype should be given
+% as plain text (it will be escaped internally). Extensions with two periods
+% are not supported.
+% \end{variable}
+%
+% \begin{variable}{\l_pdffile_source_name_str}
+% This variable is set at the begin of \cs{pdffile_embed_file:nnn}. It can be
+% (and is) used in the file dictionaries, see table~\ref{tab:filedict} for examples.
+% \end{variable}

+% \begin{variable} {\g_pdffile_embed_prop}
+% This property holds a list of embedded files. It is used by the following

+%
+% \section{\pkg{l3pdfmanagement} documentation}
+% When creating a pdf a number of objects, dictionaries and entries to
+% central \enquote{core} dictionaries must be created.
+%
+% The commands in this module offer interfaces to this core PDF dictionaries
+% They unify a number of primitives like the pdftex
+% registers and commands \cs{pdfcatalog}, \cs{pdfpageattr},
+% \cs{pdfpagesattr}, \cs{pdfinfo}, \cs{pdfpageresources}
+% and similar commands of the other backends in a backend independant way.
+%
+% The supported backends are pdflatex, lualatex, (x)dvipdfmx (latex, xelatex
+% and---starting in texlive 2021--lualatex)
+% and dvips with ps2pdf (not completely yet). dvips with distiller could work too
+% but is untested.
+%
+% That the interfaces are backend independent doesn't mean that the results and even
+% the compilation behavior is identical. The backends are too different to allow
+% this. Some backends expand arguments e.g. in a \cs{special} while other don't.
+% Some backends can insert a resource at the first compilation, while another uses
+% the aux-file and a label and so needs at least two. Some backends create and
+% manage resources automatically which must be managed manually by other backends.
+%
+% The dictionaries and resources handled by this module are inserted only
+% once in a PDF or only once per page. Examples are the Catalog dictionary,
+% the Info dictionary, the page resources. For these dictionaries and resources
+% management by the \LaTeX{} kernel is necessary to avoid
+% that packages overwrite settings from
+% other packages which would lead to clashes and incompatibilities.
+% It is therefore necessary that \emph{all} packages which want to add content to these
+% dictionaries and resources use the interface provided by this module.
+%
+% As these dictionaries and resources are so central for the PDF format values to these
+% dictionaries are always added globally. Through the interface values
+% can be added (and in many cases also removed) by users and packages,
+% but the actually writing of the
+% dictionary entries and resources to the PDF is handled by
+% the kernel code.
+%
+% The interface uses as main name to address the resources \emph{Paths}
+% which follow the names and structure described in the PDF reference. This
+% should make it easy to identify the names needed to insert a specific
+% PDF resources with the new interfaces.
+% All \emph{Paths} have names starting with an uppercase letter.
+%
+% The following tabular summarize the \emph{Paths} and which pdftex primitive they
+% replace:
+%
+% \begin{tabular}{ll}
+% Info & \cs{pdfinfo} \\
+% Catalog \& various subdictionaries & \cs{pdfcatalog} \\
+% Pages & \cs{pdfpagesattr} \\
+% Page, ThisPage & \cs{pdfpageattr} \\
+% Page/Resources/ExtGState & \cs{pdfpageresources} \\
+% Page/Resources/Shading & \cs{pdfpageresources} \\
+% Page/Resources/Pattern & \cs{pdfpageresources} \\
+% Page/Resources/ColorSpace & \cs{pdfpageresources} \\%
+% \end{tabular}
+%
+% There is no \texttt{Page/Resources/Properties} dictionary in the list,
+% because this dictionary is not filled directly, but
+% managed through side effects when setting BDC-marks.
+%
+% \subsection{User Commands}
+% To avoid problems with older documents the resource management of this
+% module is not activated unconditionally. The values are pushed out to the
+% dictionaries only if a boolean has been set to true. The state can be tested
+% with a conditional.
+% \begin{function}[EXP,pTF,added=2020-07-04]
+% {\pdfmanagement_if_active:}
+% This conditional tests if the resource management code is active.
+% \end{function}
+%
+% \begin{function}[added = 2020-04-06]
+% {\pdfmanagement_add:nnn,\pdfmanagement_add:nnx,\pdfmanagement_add:nxx}
+% \begin{syntax}
+% \cs{pdfmanagement_add:nnn} \Arg{resource path} \Arg{name} \Arg{value}
+% \end{syntax}
+% This function puts \Arg{name} \Arg{value} in the PDF resource described by
+% the symbolic name \Arg{resource path}. Technically it stores it globally in an internal
+% property lists and writes it later into the right PDF dictionary\footnote{Currently all
+% resources are PDF dictionaries, so resource and dictionary mean the same.}
+% Which values for \Arg{resource path} exist is described in the following.
+% \Arg{name} should be a PDF Name without the starting slash. Like with all
+% keys used in PDF dictionaries (see the l3pdfdict module) the name is escaped
+% with \cs{str_convert_pdfname:n} when stored.
+% \Arg{value} should be a valid PDF value for this Name in the
+% target dictionary.
+%
+%
+% The code works with all major engines but not necessarily
+% in the same way. Most importantly
+% \begin{itemize}
+% \item The expansion behaviour of the backends can differ. Some backends expand a
+% value always fully when writing to the PDF, with other backends command names
+% could end as strings in the PDF. So one should neither rely on \Arg{name}
+% \Arg{value} to be expanded nor not expanded by the backend commands.
+% \item The number of compilations needed can differ between the engines and
+% backends. Some engines have to use labels and the aux-file to setup
+% the dictionaries and so need at least two compilations to put everything
+% in place.
+% \end{itemize}
+% \end{function}
+%
+% \begin{function}[added = 2020-04-08]
+% {\pdfmanagement_show:n }
+% \begin{syntax}
+% \cs{pdfmanagement_show:n} \Arg{resource path}
+% \end{syntax}
+% This shows the content of the dictionary targetted by
+% \Arg{resource path} in the log and on the terminal if possible.
+%
+% It is not reliable for page resources as these are filled at shipout.
+%
+% It also doesn't show necessarly all the content.
+% For example most backends add automatically
+% entries to the Info dictionary.
+% \end{function}
+%
+% \begin{function}[added = 2020-04-07]
+% {
+% \pdfmanagement_remove:nn,
+% }
+% \begin{syntax}
+% \cs{pdfmanagement_remove:nn} \Arg{resource path} \Arg{name}
+% \end{syntax}
+% Removes |/|\meta{name} and its associated \meta{value} from the
+% dictionary described with \Arg{resource path}
+% The removal is global.
+% If \meta{name} is not found no change occurs,
+% \emph{i.e}~there is no need to test for the existence of a name before
+% trying to remove it.
+% Values from the special Catalog entries where the values are collected in arrays
+% can't be removed (but should ever a use case appear it could be added).
+% \end{function}
+%
+% \subsection{Description of the resource pathes}
+% \subsubsection{Info: The Info dictionary}
+% \begin{NOTE}{UF}
+% path: Info
+% The info dictionary is filled by e.g. \cs{pdfinfo}. Multiple appearances of
+% \cs{pdfinfo} are concatenated, so one could end with multiple /Title or /Author entries.
+% It is then viewer dependent which one is showed, so it is better to avoid this.
+% We therefore setup a property which is filled and written to the info
+% directory in one go. According to hyperref a few odd drivers (hvtex, dvipsone, dviwind)
+% don't support arbitrary keys, but this should be handle elsewhere.
+% As entries with empty content
+% should be omitted we add a test. The string command should perhaps escape the argument,
+% but for now we are assuming that the argument is pdf safe.
+% hyperref writes to the info dictionary at the shipout of the first page --
+% probably to catch the case that \cs{title} is issued after the begin of the document.
+% We are outputting at the last page -- this needs a second compilation but
+% this is needed anyway.
+% \end{NOTE}
+% \potentialclash If the primitive commands of the engines are used too there will
+% be double entries in the pdf (at least with the backend pdftex and luatex).
+% How pdf viewer handles this is unpredictable.
+%
+% \begin{function}
+% {
+% pdfmanagement: Info
+% }
+% \begin{syntax}
+% \cs{pdfmanagement_add:nnn} \{Info\} \Arg{name} \Arg{value}
+% \end{syntax}
+% Adds |/|\meta{name} and the \meta{value} to the Info dictionary.
+% \meta{name} should be a PDF name without the leading slash,
+% Like with all
+% keys used in PDF dictionaries (see the l3pdfdict module) the name is escaped
+% with \cs{str_convert_pdfname:n} when stored.
+% \meta{value} should be a valid pdf value. Any escaping or (re)encoding must be
+% done explicitly.
+% If a \meta{name} is used twice, only the last \meta{value}
+% set will be used. The Info dictionary is written at the end of the compilation,
+% so values can be set at any time.
+% The Info dictionary expects utf16be in the strings, so a conversion like this is
+% normally sensible:
+% \begin{verbatim}
+% \str_set_convert:Nnnn \l_tmpa_str { Grüße }{ default } {utf16/string}
+% \pdfmanagement_add:nnx {Info} {Title}{(\l_tmpa_str)}
+% \end{verbatim}
+% \end{function}
+%
+% The entries in Info dictionary are rather special as the engines/backends adds some
+% core entries, and changing or removing these entries is not always possible.
+%
+% The special entries are
+% \begin{description}
+% \item[Producer] Added by all engines and backends. Removing the entry is only possible
+% with luatex with |\pdfvariable suppressoptionalinfo 128|. Changing is possible
+% with \cs{pdfmanagement_add:nnn} with the exception of dvips/pstopdf where the entry is
+% always something like |GPL Ghostscript 9.53.3|.
+% \item[Creator] Added by all engines and backends. Removal only possible in luatex by adding
+% 16 to the bitset. Changing is possible with the management command.
+% \item[CreationDate] Added by all engines and backends. With the exception of |dvips/ps2pdf|
+% |SOURCE_DATE_EPOCH| is honored. With pdftex it is possible to suppress it with
+% |\pdfinfoomitdate = 1|, and in luatex by adding 32 to the bitset.
+% Changing is possible with the management command and will overwrite an epoch setting.
+% \item[ModDate] Added by all engines and backends with the exception of xdvipdfmx.
+% With the exception of |dvips/ps2pdf| |SOURCE_DATE_EPOCH| is honored.
+% Suppressing it is possible in pdftex with
+% |\pdfinfoomitdate = 1|, and in luatex by adding 64 to the bitset. Changing is possible with
+% the management command.
+% \item[Trapped] Added by pdftex and luatex. Removal only possible in
+% luatex by adding 256 to the bitset. Changing (and adding in the other backends) is
+% possible with the management command.
+% \item[PTEX.Fullbanner] Added by pdftex and luatex. Removal possible in pdftex with
+% |\pdfsuppressptexinfo-1|, in luatex by adding 512 to the bitset.
+% Changing is not possible.
+% \item[Title] Added by dvips/ps2pdf and set to |filename.dvi|. Removal is probably
+% not possible, but it can be overwritten with the management command.%
+% \end{description}
+% \subsubsection{Pages: The \enquote{Pages} dictionary}
+% \potentialclash As the content of this dictionary is written at the end it will
+% in pdftex and luatex overwrite values added with the primitive commands (e.g.
+% \cs{pdfpagesattr}.
+% Package authors should use the management commands instead.
+
+% By using this path with the pdfmanagement interface,
+% values can be added to the /Pages object.
+% This replaces for example \cs{pdfpagesattr}.
+%
+% \begin{function}{pdfmanagement: Pages}
+% \begin{syntax}
+% \cs{pdfmanagement_add:nnn} \{Pages\} \Arg{name} \Arg{value}
+% \end{syntax}
+%
+% Adds |/|\meta{name} \meta{value} to the |/Pages| dictionary.
+% It is always stored globally. The content is written to the pdf
+% at the end of the compilation, so values can be added, changed or
+% removed until then.
+% \meta{name} should be a valid pdf name without the leading slash,
+% \meta{value} should be a valid pdf value. Any escaping or (re)encoding must
+% be done explicitly. Some backends expand the value but this should not be
+% relied on. If a \meta{name} is used twice, only the last \meta{value}
+% set will be used.
+%
+% \end{function}
+%
+% \subsubsection{\enquote{Page} and \enquote{ThisPage}}
+% \begin{NOTE}{UF}
+% Open is the question if one need a command to set attribute on a page by page number.
+% Open is the setter for /AF (and perhaps /OutputIntents).
+% See also https://tex.stackexchange.com/questions/479812/extension-of-rotating-package-to-set-pdf-rotation
+% (should work now)
+% \end{NOTE}
+% \begin{function}[added = 2020-04-12]
+% {pdfmanagement: Page}
+% \begin{syntax}
+% \cs{pdfmanagement_add:nnn} \{Page\} \Arg{name} \Arg{value}
+% \end{syntax}
+% Values added with the path \texttt{Page} are added to the page dictionary
+% of the current page and the following pages. The current page means the page
+% on which the command is \emph{executed}. \meta{name} should be a valid pdf name
+% without the leading slash. Typical names used here are e.g.
+% \texttt{Rotate} and \texttt{CropBox}.
+% \meta{value} should be a valid pdf value.
+% Any escaping or (re)encoding must be done explicitly. Some backends expand the
+% value but this should not be relied on.
+% To avoid problems with the asynchronous page breaking
+% the command should be used after \cs{newpage} or in the header.
+% It should not be used in a float, as it will then quite probably be executed
+% on the wrong page.
+% The value is assigned directly and is always stored globally.
+% If a \meta{name} is used twice, only the last \meta{value}
+% set will be used. Names set with \cs{pdfmanagement_add:nnn}|{ThisPage}| will overwrite
+% names set with \cs{pdfmanagement_add:nnn}|{Page}| if there is a clash.
+% Values can be removed again with \cs{pdfmanagement_remove:nn}.
+% This replaces \cs{pdfpageattr}.
+% \end{function}
+% \begin{function}[added = 2020-04-12]
+% { pdfmanagement: ThisPage}
+% \begin{syntax}
+% \cs{pdfmanagement_add:nnn} \{ThisPage\} \Arg{name} \Arg{value}
+% \end{syntax}
+% Adds |/|\meta{name} \meta{value} at \emph{shipout} to the page dictionary of the
+% current page. Current page means here the \emph{shipout} page.
+% It is always stored globally.
+% If \Arg{name} has already a value set in the \texttt{Page}
+% dictionary it will be overwritten for this page.
+% \meta{name} should be a valid pdf name without the leading slash,
+% \meta{value} should be a valid pdf value. Any escaping or (re)encoding must be
+% done explicitly. If a \meta{name} is used twice, only the last \meta{value}
+% set will be used.
+% With the engine pdflatex (at least) a second compilation is needed.
+% Values added to \texttt{ThisPage} can not be removed. It is not possible to
+% show the content of this dictionary with \cs{pdfmanagement_show:n}.
+% \end{function}
+% \subsubsection{\enquote{Page/Resources}: ExtGState, ColorSpace, Shading, Pattern}
+% \begin{NOTE}{UF}
+% Only for pdf/luatex and xdvipdfmx backend- and pdf-code is needed to add values
+% to these resources.
+% With dvips the resources are added through high-level code (e.g. transparency), so the
+% backend/pdf commands are no-ops.
+% For every resources there is only one object. References to these objects are added to
+% all pages starting from the page where the first time something has been added to the
+% resource and to all XObjects. For luatex and pdftex it must be done together
+% with the /Properties, see above.
+% I don't see a need to set e.g. /ColorSpace page wise: preflight handles this
+% fine, see experiment colorspace-resources.
+% As pgf does the same, there is a need to patch it for now. Ditto for package colorspace.
+% \end{NOTE}
+% \begin{function}[updated = 2020-04-10]
+% {
+% pdfmanagement: Page/Resources/ExtGState,
+% pdfmanagement: Page/Resources/ColorSpace,
+% pdfmanagement: Page/Resources/Shading,
+% pdfmanagement: Page/Resources/Pattern,
+% }
+% \begin{syntax}
+% \cs{pdfmanagement_add:nnn} \{Page/Resources/\meta{resource}\} \Arg{name} \Arg{value}
+% \end{syntax}
+% Adds |/|\meta{name} \meta{value} to the page resource \meta{resource}.
+% \meta{resource} can be |ExtGState|, |ColorSpace|, |Pattern| oder |Shading|.
+% The values are always stored globally. The content is written to the pdf
+% at the end of the compilation, so values can be added until then.
+% \meta{name} should be a valid pdf name without the leading slash,
+% \meta{value} should be a valid pdf value for the resource.
+% Any escaping or (re)encoding must be done explicitly. If a \meta{name} is
+% used twice, only the last \meta{value} set will be used.
+%
+% With the dvips backend the command does nothing: these resources are managed by
+% ghostscript or the distiller if e.\,g. transparency is used.
+%
+% The resources are added to all pages starting with the first where something has
+% been added to a resources. That means that for example
+% all ExtGState resources are combined in one
+% dictionary object and every page with a ExtGState resource refer to this object%
+% \footnote{This is similar to how pgf handles this resources}.
+%
+% \potentialclash The primitive commands (e.g. \cs{pdfpageresources})
+% to set the resources should not be used
+% together with this code as the calls will overwrite each other and values
+% will be lost. This means that currently there are clashes with the packages tikz,
+% transparent and colorspace.
+% \end{function}
+% \subsubsection{\enquote{Catalog} \& subdirectories}
+% \begin{NOTE}{UF}
+% Perhaps some tools to create the AF-file specification dictionaries is useful.
+% Open for now:
+% /Extensions (dict, pdf 2.0)
+% /Dests ? difference to subdict in Names?
+% /DSS (dict, pdf 2.0)
+% /Acroform/DR/ExtGState etc probably unneeded.
+% \end{NOTE}
+% The catalog is a central dictionary in a PDF with a number of subdictionaries.
+% Entries to the top level of the catalog can be added with\\
+% |\pdfmanagement_add:nnn {Catalog}|\Arg{Name}\Arg{Value}.
+% Entries to subdictionaries by using in the first
+% argument one of the pathes described later.
+% The entries in the catalog have varying requirements regarding the
+% PDF management. Some entries (like \texttt{/Lang}) are simple values
+% where new values should
+% overwrite existing values, other like for example \texttt{/OutputIntents}
+% can contain a number of values and can be filled from more than one source.
+% In some cases the values that needs to be added are not at the top-level
+% but in some subsubdictionary or are actually part of an array.
+% To handle the pdf management uses a variety of internal, special handlers.
+%
+% \potentialclash In some cases entries are added implicitly.
+% For example entries to the name
+% tree of the \texttt{/EmbeddedFiles} key in the \texttt{/Names} directory are
+% added with the commands of the \texttt{l3pdffile} module. This clashes with
+% e.g. the embedfile package which should not be used!
+%
+%
+% \paragraph{Entries at the top level of the catalog}
+% The Names in the following tabular are entries that are added to the
+% top level of the catalog.
+%
+% If \meta{Name} gets assigned a value more than once the last one wins.
+% There is no check that the values have the correct type and format.
+% It is up to the user to ensure that the value does what is intended.
+%
+% The required PDF version is only mentioned if it is larger than 1.5.
+%
+% Example: |\pdfmanagement_add:nnn {Catalog}{PageMode}{/UseNone}|
+%
+% \medskip

+% \par\medskip
+%
+% \paragraph{Simple entries in subdictionaries of the catalog}
+% The following resource pathes have been predeclared and allow to
+% add values to the respective subdictionaries of the catalog. The
+% names of the dictionaries follow the naming and location of the dictionaries
+% in the PDF reference.
+% If \meta{Name} gets assigned two values the last one wins.

+%
+% \section{\pkg{l3pdfmeta} documentation}
+% This module sets up some tools and commands needed
+% for PDF standards in general.
+% The goal is to collect the requirements and to provide code to check and fulfill them.
+%
+% In future is will probably also contain
+% code to setup XMP-metadata.
+% Until then XMP-metadata can be added by one of two mutual incompatible packages:
+% \pkg{hyperxmp} and \pkg{pdfx}. Both
+% packages aren't yet compatible with the new PDF management,
+% but for \pkg{hyperxmp} some patches are provided, so the basic functions works.
+%
+% \begin{NOTE}{UF}
+% This module should not replace both packages.
+% Regarding XMP-metadata its goal
+% is to create a skeleton metadata stream, add some core default values
+% and to define interfaces that allows other packages
+% to add data to this metadata and so to extend them.
+% The problems to solve here are
+% \begin{itemize}
+% \item which tree structure is sensible
+% \item how to escape if needed the input (or which tools are needed to allow
+% the users to correctly escape their input)
+% \item how interface to input data should look
+% \end{itemize}
+% \end{NOTE}
+%
+% \subsection{Verifying requirements of PDF standards}
+%
+% Standards like pdf/A set requirements on a PDF: Some things have be in the PDF,
+% e.g. the catalog has to contain a /Lang entry and an colorprofile and
+% an /OutputIntent, some other things are forbidden or restricted, e.g.
+% the action dictionary of an annotation should not contain Javascript.
+%
+% The \pkg{l3pdfmeta} module collects a number of relevant requirements,
+% tries to enforce the ones which can be enforced and offers some tools
+% for package authors to test if an action is allowed in the standard or not.
+%
+% This is work in progress and more tests will be added. But it should be noted
+% that it will probably never be possible to prevent all forbidden actions
+% or enforce all required ones or even to simply check all of them.
+% The commands here don't replace a check with an external validator.
+%
+% Verifying against a PDF-standard involves two different task:
+%
+% \begin{itemize}
+% \item Check if you are allowed to ignore the requirement.
+% \item Decide which action to take if the answer to the first question is NO.
+% \end{itemize}
+%
+% The following conditionals address the first task. Because of the second task
+% a return value |FALSE| means that the standard requires you to do some
+% special action. |TRUE| means that you can ignore this
+% requirement.\footnote{One could also make the logic the
+% other way round---there are arguments for both---but I had to decide.}
+%
+% In most cases it only matters if a requirement is in the standard,
+% for example |Catalog_no_OCProperties| means \enquote{don't use |/OCProperties|
+% in the catalog}. For a small number of requirements it is also needed to
+% test a user value against a standard value. For example, |named_actions|
+% restricts the allowed named actions in an annotation of subtype |/Named|,
+% in this case it is needed to check not only if the requirement is
+% in the standard but also if the user value is in the allowed list.
+%
+% \begin{function}[EXP,pTF]{\pdfmeta_standard_verify:n}
+% \begin{syntax}
+% \cs{pdfmeta_standard_verify:n}\Arg{requirement}
+% \end{syntax}
+%
+% This checks if \meta{requirement} is listed in the standard.
+% |FALSE| as result means that the requirement is in the standard and
+% that probably some special action is required---which one depends
+% on the requirement, see the descriptions below.
+% |TRUE| means that the requirement is not there and so no special
+% action is needed.
+% This check can be used for simple requirements where neither
+% a user nor a standard value is of importance.
+% \end{function}
+%
+% \begin{function}[TF]{\pdfmeta_standard_verify:nn}
+% \begin{syntax}
+% \cs{pdfmeta_standard_verify:nn}\Arg{requirement}\Arg{value}
+% \end{syntax}
+%
+% This checks if \meta{requirement} is listed in the standard,
+% if yes it tries to find a predefined test handler for
+% the requirement and passes \meta{value} and the value recorded
+% in the standard to it. The handler returns |FALSE| if some special
+% action is needed (e.g. if \meta{value} violates the rule)
+% and |TRUE| if no special action is needed. If no handler exists
+% this commands works like \cs{pdfmeta_standard_verify:n}.
+% \end{function}
+%
+% In some cases one needs to query the value in the standard,
+% e.g. to correct a wrong minimal PDF version you need to know
+% which version is required by |min_pdf_version|.
+% For this two commands to access the value are provided:
+%
+% \begin{function}[EXP]{\pdfmeta_standard_item:n}
+% \begin{syntax}
+% \cs{pdfmeta_standard_item:n}\Arg{requirement}
+% \end{syntax}
+% This retrieves the value of \meta{requirement} and leaves it in the input.
+% If the requirement isn't in the standard the result is empty,
+% that means that requirements not in the standard and
+% requirement without values can not be distinguished here.
+% \end{function}
+%
+%
+% \begin{function}{\pdfmeta_standard_get:nN}
+% \begin{syntax}
+% \cs{pdfmeta_standard_get:nN}\Arg{requirement} \meta{tl var}
+% \end{syntax}
+% This retrieves the value of \meta{requirement} and stores
+% it in the \meta{token list variable}.
+% If the \meta{requirement} is not found the special
+% value |\q_no_value| is used.
+% The \meta{token list variable} is assigned locally.
+% \end{function}
+%
+%
+% The following describe the requirements which can be currently tested.
+% Requirements with a value should use \cs{pdfmeta_standard_verify:nn}
+% or \cs{pdfmeta_standard_verify:nnN} to test a local value against the standard.
+% The rule numbers refer to \url{https://docs.verapdf.org/validation/pdfa-part1/}
+%
+% \subsubsection{Simple tests without handler}
+%
+% \begin{description}
+%
+% \item[|outputintent_A|] requires to embed a color profile and
+% reference it in a /Outputintent and that all output intents reference
+% the same colorprofile. The value stores the subtype.
+% {\em This requirement is detected and fulfilled by \pkg{l3pdfmeta} if the
+% provided interface in \cs{DeclareDocumentMetadata} is used, see below}.
+%
+% \item[|annot_flags|] in annotations the |Print| flag should be true,
+% |Hidden|, |Invisible|, |NoView| should be false.
+% {\em This requirement is detected and set by \pkg{l3pdfmeta} for annotations
+% created with the \pkg{l3pdfannot}.
+% A new check is only needed if the flags are changed
+% or if links are created by other means.}
+%
+% \item[|no_encryption|] don't encrypt
+% \item[|no_external_content|] no |/F|, |/FFilter|, or |/FDecodeParms|
+% in stream dictionaries
+% \item[|no_embed_content|] no |/EF| key in filespec, no |/Type/EmbeddedFiles|.
+% \emph{This will be checked in future by \pkg{l3pdffiles}
+% for the files it embeds.}
+% The restrictment is set for only PDF/A-1b.
+% PDF/A-2b and PDF/A3-b lifted this restriction: PDF/A-2b allows
+% to embed other PDF documents conforming to either PDF/A-1 or PDF/A-2,
+% and PDF/A-3 allows any embedded files. I don't see a way to test the
+% PDF/A-2b requirement so currently it will simply allow everything. Perhaps
+% a test for at least the PDF-format will be added in future.
+% \item[|Catalog_no_OCProperties|] don't add |/OCProperties| to the catalog
+% {\em l3pdfmeta removes this entry at the end of the document}
+% \item[|annot_widget_no_AA|] (rule 6.6.2-1)
+% no AA dictionary in widget annotation,
+% this will e.g. be checked by the new hyperref driver.
+% \item[|annot_widget_no_A_AA|] (rule 6.9-2) no A and AA dictionary in widget.
+% \item[|form_no_AA|] (6.9-3) no /AA dictionary in form field
+% \end{description}
+%
+% \subsubsection{Tests with values and special handlers}
+%
+% \begin{description}
+%
+% \item[|min_pdf_version|] stores the minimal PDF version.
+% It should be checked against the current PDF version (\cs{pdf_version:}).
+% A failure means that the version should be changed.
+% This check is done by \pkg{l3pdfmeta} when the version is set with
+% \cs{DeclareDocumentMetadata} so more checks are only needed if the version is changed later.
+%
+% \item[|named_actions|] this requirement restricts the list of
+% allowed named actions to |NextPage|, |PrevPage|, |FirstPage|, |LastPage|.
+% The check should supply the named action without slash
+% (e.g. |View| (failure) or |NextPage| (pass)).
+%
+% \item[|annot_action_A|] (rule 6.6.1-1) this requirement restricts
+% the allowed subtypes of the
+% |/A| dictionary of an action. The check should supply the user
+% subtype without slash e.g. as |GoTo| (pass) or |Movie| (failure).
+% \end{description}
+%
+% \subsection{Colorprofiles and OutputIntent}
+%
+% The pdf/A standards require that a color profile is embedded and
+% referenced in the catalog in the |/OutputIntent| array.
+%
+% The problem is that the pdf/A standards also require, that if the PDF has more then
+% one entry in the |/OutputIntent| array (which is allowed), their |/DestOutputProfile|
+% should all reference the same color profile\footnote{see rule 6.2.2-2 at
+% \url{https://docs.verapdf.org/validation/pdfa-part1/}}.
+%
+% Enforcing this fully is impossible if entries are added manually by users or
+% packages with |\pdfmanagement_add:nnn {Catalog}{OutputIntents}{|\meta{object reference}|}|
+% as it is difficult to inspect and remove entries from the |/OutputIntent| array.
+%
+% So we provide a dedicated interface to avoid the need of manual
+% user settings and allow the code to handle the requirements of the standard.
+% The interface doesn't handle yet all finer points for PDF/X standards, e.g.
+% named profiles, it is meant as a starting point to get at least PDF/A validation
+% here.
+%
+% \begin{NOTE}{UF}
+% The interface has to handle the following points:
+% \begin{itemize}
+% \item We have to assume that some documents wants to add more
+% than one OutputIntent with varying subtypes.
+% \item While currently only |/GTS_PDFA1| and |/GTS_PDFX| seem to
+% be relevant, we have to assume that the list of subtypes is open.
+% \item But we can imho assume that every subtype is there at most once.
+% \item The referenced color profile can be used also other means, e.g. an /ICCBased
+% color space. We must avoid that it is embedded twice in this case.
+% This will need coordination with l3color. It should probably provide the
+% code to embed the profile.
+% \item While we can predeclare some standard icc-profiles, an interface to
+% setup more is needed. This is currently not handled, as it needs
+% coordination with a setup in l3color too.
+% \item The implementation doesn't really handle yet all finer points for pdf/X
+% see \url{tn0002_color_in_pdfa-1_2008-03-141.pdf}
+% \end{itemize}
+% \end{NOTE}
+% The interface looks like this
+%
+% \begin{verbatim}
+% \DeclareDocumentMetadata
+% {
+% %other options for example pdfstandard
+% colorprofiles=
+% {
+% A = sRGB.icc, %or a or longer GTS_PDFA1 = sRGB.icc
+% X = FOGRA39L_coated.icc, % or x or longer GTS_PDFX
+% ISO_PDFE1 = whatever.icc
+% }
+%
+% }
+% \end{verbatim}
+%
+% |sRGB.icc| and |FOGRA39L_coated.icc| (from the \pkg{colorprofiles} package
+% are predefined and will work directly\footnote{The \texttt{dvips} route
+% will require that \texttt{ps2pdf} is called with \texttt{-dNOSAFER},
+% and that the color profiles are in the current folder as \texttt{ps2pdf} doesn't
+% use \texttt{kpathsea} to find them.}. |whatever.icc| will need special setup in
+% the document preamble to declare the values for the
+% |OutputIntent| dictionary, but the interface hasn't be added yet. This will be
+% decided later.
+%
+%
+% If an A-standard is detected or set which requires
+% that all |/DestOutputProfile| reference the same
+% color profile, the setting is changed to the equivalent of
+%
+% \begin{verbatim}
+% \DeclareDocumentMetadata
+% {
+% %other options
+% pdfstandard=A-2b,
+% colorprofiles=
+% {
+% A = sRGB.icc, %or longer GTS_PDFA1 = sRGB.icc
+% X = sRGB.icc,
+% ISO_PDFE1 = sRGB.icc
+% }
+%
+% }
+% \end{verbatim}
+%
+% The pdf/A standards will use |A=sRGB.icc| by default, so this doesn't
+% need to be declared explicitly.
+%

+% \begin{macrocode}
+\prop_new:N \g_@@_standard_prop
+% \end{macrocode}
+% \end{variable}
+% \subsubsection{Functions to check a requirement}
+% At first two commands to get the standard value if needed:
+% \begin{macro}[EXP]{\pdfmeta_standard_item:n}
+% \begin{macrocode}
+\cs_new:Npn \pdfmeta_standard_item:n #1
+ {
+ \prop_item:Nn \g_@@_standard_prop {#1}
+ }
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\pdfmeta_standard_get:nN}
+% \begin{macrocode}
+\cs_new_protected:Npn \pdfmeta_standard_get:nN #1 #2
+ {
+ \prop_get:NnN \g_@@_standard_prop {#1} #2
+ }
+% \end{macrocode}
+% \end{macro}
+% Now two functions to check the requirement. A simple and one value/handler based.
+% \begin{macro}[pTF]{\pdfmeta_standard_verify:n}
+% This is a simple test is the requirement is in the prop.
+% \begin{macrocode}
+\prg_new_conditional:Npnn \pdfmeta_standard_verify:n #1 {T,F,TF}
+ {
+ \prop_if_in:NnTF \g_@@_standard_prop {#1}
+ {
+ \prg_return_false:
+ }
+ {
+ \prg_return_true:
+ }
+ }
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}[TF]{\pdfmeta_standard_verify:nn}
+% This allows to test against a user value. It calls a test handler if this
+% exists and passes the user and the standard value to it. The test
+% handler should return true or false.
+% \begin{macrocode}
+\prg_new_protected_conditional:Npnn \pdfmeta_standard_verify:nn #1 #2 {T,F,TF}
+ {
+ \prop_if_in:NnTF \g_@@_standard_prop {#1}
+ {
+ \cs_if_exist:cTF {@@_standard_verify_handler_#1:nn}
+ {
+ \exp_args:Nnnx
+ \use:c
+ {@@_standard_verify_handler_#1:nn}
+ { #2 }
+ { \prop_item:Nn \g_@@_standard_prop {#1} }
+ }
+ {
+ \prg_return_false:
+ }
+ }
+ {
+ \prg_return_true:
+ }
+ }
+% \end{macrocode}
+% \end{macro}
+%
+% Now we setup a number of handlers.
+%
+% The first actually ignores the user values and tests against the
+% current pdf version. If this is smaller than the minimum we report a failure.
+% |#1| is the user value, |#2| the reference value from the standard.
+% \begin{macro}{\@@_standard_verify_handler_min_pdf_version:nn}
+% \begin{macrocode}
+%
+\cs_new_protected:Npn \@@_standard_verify_handler_min_pdf_version:nn #1 #2
+ {
+ \pdf_version_compare:NnTF <
+ { #2 }
+ {\prg_return_false:}
+ {\prg_return_true:}
+ }
+% \end{macrocode}
+% \end{macro}
+% The next checks if the user value is in the list and returns a failure if not.
+% \begin{macro}{\@@_standard_verify_handler_named_actions:nn}
+% \begin{macrocode}
+
+\cs_new_protected:Npn \@@_standard_verify_handler_named_actions:nn #1 #2
+ {
+ \tl_if_in:nnTF { #2 }{ #1 }
+ {\prg_return_true:}
+ {\prg_return_false:}
+ }
+% \end{macrocode}
+% \end{macro}
+% The next checks if the user value is in the list and returns a failure if not.
+% \begin{macro}{\@@_standard_verify_handler_annot_action_A:nn}
+% \begin{macrocode}
+\cs_new_protected:Npn \@@_standard_verify_handler_annot_action_A:nn #1 #2
+ {
+ \tl_if_in:nnTF { #2 }{ #1 }
+ {\prg_return_true:}
+ {\prg_return_false:}
+ }
+% \end{macrocode}
+% \end{macro}
+% This check is probably not needed, but for completeness
+% \begin{macro}{\@@_standard_verify_handler_outputintent_subtype:nn}
+% \begin{macrocode}
+\cs_new_protected:Npn \@@_standard_verify_handler_outputintent_subtype:nn #1 #2
+ {
+ \tl_if_eq:nnTF { #2 }{ #1 }
+ {\prg_return_true:}
+ {\prg_return_false:}
+ }
+% \end{macrocode}
+% \end{macro}
+% \subsubsection{Enforcing requirements}
+% A number of requirements can sensibly be enforced by us.
+% \paragraph{Annot flags}
+% pdf/A require a number of settings here, we store them in a command which
+% can be added to the property of the standard:
+% \begin{macrocode}
+\cs_new_protected:Npn \@@_verify_pdfa_annot_flags:

+%
+% \subsubsection{Colorprofiles and Outputintents}
+% The following provides a minimum of interface to add a color profile
+% and an outputintent need for PDF/A for now. There will be need to extend it later,
+% so we try for enough generality.
+%
+% Adding a profile and an intent is technically easy:
+% \begin{enumerate}
+% \item Embed the profile as stream with
+% \begin{verbatim}
+% \pdf_object_unnamed_write:nn{fstream} {{/N~4}{XXX.icc}}
+% \end{verbatim}
+% \item Write a |/OutputIntent| dictionary for this
+% \begin{verbatim}
+% \pdf_object_unnamed_write:nx {dict}
+% {
+% /Type /OutputIntent
+% /S /GTS_PDFA1 % or GTS_PDFX or ISO_PDFE1 or ...
+% /DestOutputProfile \pdf_object_ref_last: % ref the color profile
+% /OutputConditionIdentifier ...
+% ... %more info
+% }
+% \end{verbatim}
+% \item Reference the dictionary in the catalog:
+% \begin{verbatim}
+% \pdfmanagement_add:nnx {Catalog}{OutputIntents}{\pdf_object_ref_last:}
+% \end{verbatim}
+% \end{enumerate}
+% But we need to do a bit more work, to get the interface right.
+% The object for the profile should be named, to allow l3color to reuse it
+% if needed. And we need container to store the profiles, to handle the
+% standard requirements.
+%
+% \begin{variable}{\g_@@_outputintents_prop}
+% This variable will hold the profiles for the subtypes. We assume
+% that every subtype has only only color profile.
+% \begin{macrocode}
+\prop_new:N \g_@@_outputintents_prop
+% \end{macrocode}
+% \end{variable}
+% Some keys to fill the property.
+% \begin{macrocode}
+\keys_define:nn { document / metadata }
+ {
+ colorprofiles .code:n =
+ {
+ \keys_set:nn { document / metadata / colorprofiles }{#1}
+ }

+ }
+ }

+ \prop_gput:Nnn \g_@@_outputintents_prop
+ { \l_keys_key_str } {#1}
+ }
+ }
+ }
+% \end{macrocode}
+% At first we setup our two default profiles. This is internal as
+% the public interface is still undecided.
+% \begin{macrocode}
+\pdfdict_new:n {l_pdfmeta/outputintent}
+\pdfdict_put:nnn {l_pdfmeta/outputintent}
+ {Type}{/OutputIntent}
+\prop_const_from_keyval:cn { c_@@_colorprofile_sRGB.icc}

+ curves~A~(CMY)~and~B~(K)}
+ ,RegistryName=http://www.fogra.org
+ ,N = 4
+ }
+% \end{macrocode}
+% \begin{macro}{\@@_embed_colorprofile:n,\@@_write_outputintent:nn}
+% The commands embed the profile, and write the dictionary and add it to
+% the catalog. The first command should perhaps be moved to l3color
+% as it needs such profiles too. We used named objects so that we can
+% check if the profile is already there. This is not full proof if pathes are
+% used.
+% \begin{macrocode}
+\cs_new_protected:Npn \@@_embed_colorprofile:n #1%#1 file name

+ {
+ {/N\c_space_tl
+ \prop_item:cn{c_@@_colorprofile_#1}{N}
+ }
+ {#1}
+ }

+ }
+
+\cs_new_protected:Npn \@@_write_outputintent:nn #1 #2 %#1 file name, #2 subtype
+ {
+ \group_begin:

+ {DestOutputProfile}
+ {\pdf_object_ref:n{ __color_icc_ #1 }}
+ \clist_map_inline:nn { OutputConditionIdentifier, Info, RegistryName }
+ {
+ \prop_get:cnNT

+ { ##1 }
+ \l_@@_tmpa_tl

+ \pdfdict_put:nnx
+ {l_pdfmeta/outputintent}{##1}{\l_@@_tmpa_str}
+ }
+ }
+ \pdf_object_unnamed_write:nx {dict}{\pdfdict_use:n {l_pdfmeta/outputintent} }
+ \pdfmanagement_add:nnx {Catalog}{OutputIntents}{\pdf_object_ref_last:}
+ \group_end:
+ }
+% \end{macrocode}
+% \end{macro}
+% Now the verifying code.
+% If no requirement is set we simply loop over the property
+% \begin{macrocode}
+
+\AddToHook{begindocument/end}
+ {
+ \pdfmeta_standard_verify:nTF {outputintent_A}
+ {
+ \prop_map_inline:Nn \g_@@_outputintents_prop
+ {
+ \@@_embed_colorprofile:n
+ {#2}
+ \@@_write_outputintent:nn
+ {#2}
+ {#1}
+ }
+ }
+% \end{macrocode}
+% If an output intent is required for pdf/A we need to ensure, that the key of
+% default subtype has a value, as default we take sRGB.icc.
+% Then we loop but take always the same profile.
+% \begin{macrocode}
+ {

+%
+% This module collects a number of candidate commands for the l3pdf module
+%
+% \begin{function}[EXP,added=2021-02-14]
+% {\pdf_name_from_unicode_e:n}
+% \begin{syntax}
+% \cs{pdf_name_from_unicode_e:n} \Arg{content}
+% \end{syntax}
+% This converts \meta{content} to a format suitable for a PDF Name.
+% It will first expand the content with \cs{text_expand:n} and
+% then escape it in the way needed in a PDF Name with
+% \cs{str_convert_pdfname:e}, and at last prepend a slash before.
+% Typically such names use only ascii,
+% but non-ascii is supported, but should be utf8 encoded. For example\\
+% |\pdf_name_from_unicode_e:n {A~B\c_percent_str C\c_hash_str D€}}|\\
+% will output |/A#20B#25C#23D#E2#82#AC|.
+% \end{function}
+% \begin{function}[added=2020-07-04]
+% {\pdf_string_from_unicode:nnN}
+% \begin{syntax}
+% \cs{pdf_string_from_unicode:nnN} \Arg{format} \Arg{content} \Arg{tlvar}
+% \end{syntax}
+% This converts \meta{content} following the rules defined by \meta{format} and stores
+% the result in \meta{tlvar}. The assignment is done locally.
+% Non-ascii input should be utf8 encoded.
+% Currently the following formats exist:
+% \begin{description}
+% \item[utf8/string-raw]
+% this converts with \cs{str_set_convert:Nnnn} into utf8/string.
+% \item[utf8/string]
+% this converts into utf8/string and adds parentheses around the result.%
+% \item[utf8/URI-raw]
+% this converts with \cs{str_set_convert:Nnnn} into utf8/url and
+% then replaces reserved and digits back from the percent encoding. Parentheses
+% are escaped.
+% \item[utf8/URI]
+% this converts into utf8/URI and adds parentheses around the result.%
+% \item[utf16/string-raw]
+% this converts with \cs{str_set_convert:Nnnn} into utf16/string.
+% \item[utf16/string]
+% this converts into utf16/string and adds parentheses around the result.
+% \item[utf16/hex-raw]
+% this converts into utf16/hex
+% \item[utf16/hex]
+% this converts into utf16/hex and adds bracket around the result.
+% \end{description}
+% \end{function}
+%
+% \subsection{BDC operator / Properties resource}
+% \begin{NOTE}{UF}
+% we need a switch for the case that the resource should be added to
+% xform resource instead of a page resources, see pdfbase.sty
+% - xdvipdfmx: looks fine, the resource is added to the xform resource automatically
+% - pdftex should now work okay too
+% \end{NOTE}
+% Entries to the /Properties dictionary in the page resources can
+% be added with dvips only through side-effects: if a BDC-mark is created
+% dvips/ghostscript will automatically create the necessary objects and names.
+% To get a sensible abstraction the code does the same for the other backends if the
+% core management code has been activated. This means that the behaviour
+% of the command is different then. The \cs{pdf_bdcobject:..} should only be used
+% if the management is active.
+% \begin{function}[updated = 2020-07-03]
+% {
+% \pdf_bdc:nn
+% }
+% \begin{syntax}
+% \cs{pdf_bdc:nn} \Arg{tag} \Arg{dictionary content}
+% \end{syntax}
+% This command adds a BDC marked content operator to the current page stream.
+% \meta{tag} is the tag of this operator (without the leading slash),
+% \meta{dictionary content} is the content of the second argument.
+% If the PDF resource management is active an dictionary object with the
+% content is created and referenced with a name in the BDC operator.
+% Without the resource management the content is used directly. It then
+% depends on the backend how it is handled: with dvips a name is used
+% while the pdfmode engines and dvipdfmx write the content into the stream.
+%
+% \end{function}
+% \begin{function}[added = 2020-07-03]
+% {
+% \pdf_bdcobject:nn
+% }
+% \begin{syntax}
+% \cs{pdf_bdcobject:nn} \Arg{tag} \Arg{object name}
+% \end{syntax}
+% This command adds a BDC marked content operator to the current page stream.
+% \meta{tag} is the tag of this operator (without the leading slash),
+% \meta{object name} is a the name of an dictionary object reserved with
+% \cs{pdf_object_new:nn} and filled with \cs{pdf_object_write:n} with
+% the properties of the BDC. Reusing a predefined object can save space
+% but the command works correctly
+% only if the resources management has been activated and should be used only
+% if this can be ensured.
+% \end{function}
+% \begin{function}[updated = 2020-07-03]
+% {
+% \pdf_bdcobject:n
+% }
+% \begin{syntax}
+% \cs{pdf_bdcobject:n} \Arg{tag}
+% \end{syntax}
+% This command adds a BDC marked content operator to the current page stream.
+% \meta{tag} is the tag of this operator (without the leading slash).
+% As object this commands uses the last anonymous dictionary object created with
+% \cs{pdf_object_now:nn}. It lies in the responsibility of the user that the last
+% object is the wanted one. Like with \cs{pdf_bdcobject:nn} the command works correctly
+% only if the resources management has been activated and should be used only
+% if this can be ensured.
+% \end{function}
+% \begin{function}[added = 2019-10-17]
+% {
+% \pdf_bmc:n
+% }
+% \begin{syntax}
+% \cs{pdf_bmc:n} \Arg{tag}
+% \end{syntax}
+% This command created a BMC marked content operator. The argument is the
+% tag without the leading slash. It can be e.g. used for simple artifact
+% markers.
+% \end{function}
+% \begin{function}[added = 2019-06-30]
+% {
+% \pdf_emc:
+% }
+% \begin{syntax}
+% \cs{pdf_emc:}
+% \end{syntax}
+% This command closes the BDC marked content operator opened with \cs{pdf_bdc:nn}.
+% It should be on the same page as the bdc-command.
+%
+% \begin{verbatim}
+% \pdf_object_new:nn {objA}{dict}

+% \maketitle
+% \begin{documentation}
+%
+% \section{\pkg{l3pdfxform} documentation}
+% This module contains a number of commands to create \enquote{form XObjects},
+% for which pdf\TeX{} introduced the short name \enquote{xforms}.
+%
+% The status is still beta, so the style itself is currently named
+% \pkg{l3pdfxform-beta}. Missing is for example code for the dvips route.
+% Probably some of the function will also need to be enhanced by hooks.
+%
+% \begin{function}[added = 2019-08-05,updated=2021-02-14]
+% {
+% \pdfxform_new:nnn
+% }
+% \begin{syntax}
+% \cs{pdfxform_new:nnn} \Arg{name} \Arg{attributes} \Arg{content}
+% \end{syntax}
+% This command create a new form XObject that can be used as appearance or
+% directly later.
+% If the \meta{content} contains BDC-marks it should \emph{not} be given as a
+% previously typeset box, but directly so that the names of the
+% BDC-marks can be added to the resources of the xform. The xform will automatically
+% include the resources of the current page.
+% The content will be typeset in a hbox. With pdflatex and luatex
+% the surrounding color is \emph{not} stored in the form XObject
+% but should be if wanted added e.g. with |\color_select:n{.}|. This keeps
+% the option of color injection open.
+% \end{function}
+% \begin{function}[added = 2019-08-05]
+% {
+% \pdfxform_use:n
+% }
+% \begin{syntax}
+% \cs{pdfxform_use:n} \Arg{name}
+% \end{syntax}
+% This command uses (typesets) a previously created form XObject.
+% If the surrounding color is different, it is injected in the form XObject with the
+% engines pdftex or luatex.
+% \end{function}
+% \begin{function}[EXP,added = 2019-08-05]
+% {
+% \pdfxform_ref:n
+% }
+% \begin{syntax}
+% \cs{pdfxform_ref:n} \Arg{name}
+% \end{syntax}
+% Inserts the appropriate information to reference the xform \meta{name}
+% in for example appearance dictionaries.
+% \end{function}
+% \begin{function}[EXP,added = 2019-08-05]
+% {
+% \pdfxform_wd:n, \pdfxform_ht:n, \pdfxform_dp:n
+% }
+% \begin{syntax}
+% \cs{pdfxform_wd:n} \Arg{name}
+% \end{syntax}
+% These command give back the sizes of the form XObject. The values are stored in
+% tl-variables with the unit pt and not in dimensions!
+% \end{function}
+% \begin{function}[EXP,pTF,added = 2020-04-29]
+% {
+% \pdfxform_if_exist:n
+% }
+% \begin{syntax}
+% \cs{pdfxform_if_exist_p:n} \Arg{name}
+% \cs{pdfxform_if_exist:NTF} \meta{name} \Arg{true code} \Arg{false code}
+% \end{syntax}
+% These command tests if an xform with name \Arg{name} has been already defined.
+% \end{function}%

+% \subsection{Form XObject (pdfxform)}
+% \begin{NOTE}{UF}
+% - As in dvi mode the xform is immediate, this is done for pdftex/luatex too.
+% If needed a delayed version can be added later.
+% - the argument for attributes is needed to add e.g. /StructParents
+% - it is not clear if an argument for additional resources is needed, probably they
+% should / need to be added automatically.
+% - code for adding ExtGState etc to the local resource is missing, will be
+% added when the object name is clear.
+% - should the size be stored in dim or tl?
+% - dvips implementation is missing for ideas: pdfbase, atfi-dvips.def,

+% \begin{documentation}
+%
+% \section{\pkg{ltdocinit} documentation}
+% This small module defines \cs{DeclareDocumentMetadata} and the related keys.
+% It also defines commands to store document properties in a global container.
+%
+% \subsection{\cs{DeclareDocumentMetadata}}
+%
+% \begin{function}{\DeclareDocumentMetadata}
+% \begin{syntax}
+% \cs{DeclareDocumentMetadata}\Arg{key-value list}
+% \end{syntax}
+% \end{function}
+%
+% Currently there is no dedicated location to declare settings concerning
+% a document as a whole. Settings are placed somewhere in the preamble or
+% with the class options or even with some package options.
+% For some settings this can be too late,
+% for example the pdf version can no longer be changed if a
+% package has used code which already opened the PDF.
+%
+% \cs{DeclareDocumentMetadata} as a new command
+% should unify such settings in one place.
+% It should be used before \cs{documentclass}, directly after
+% loading \pkg{pdfmanagement-testphase}. \cs{DeclareDocumentMetadata}
+% can be used more than once.
+%
+% The keys defined for \cs{DeclareDocumentMetadata}
+% currently allows to set the PDF version, to set the PDF \texttt{/Lang},
+% to uncompress a pdf, to set the language and to declare a few PDF standards
+% and some colorprofiles.
+%
+% \cs{DeclareDocumentMetadata} is also used to
+% activate the new PDF management code and it loads
+% a number of required files for the PDF management code.
+% As this forces the loading of the backend files, a backend
+% which can't be detected automatically like |dvipdfmx|,
+% must be set in the first \cs{DeclareDocumentMetadata}.
+%
+% Currently the following keys are implemented
+%
+% \begin{description}
+% \item[\texttt{backend}] passes the backend name to expl3.
+% This will probably be extended to pass the value also to packages.
+% \item[\texttt{pdfversion}] e.g. \texttt{pdfversion=1.7}
+% \item[\texttt{uncompress}] no value. Forces an uncompressed pdf.
+% \item[\texttt{lang}] to set the Lang entry in the Catalog.
+% E.g. \texttt{lang=de-DE}. The initial value is |en-US|
+% \item[\texttt{pdfstandard}] Choice key to set the pdf standard.
+% Currently |A-1b|, |A-2b| and |A-3b| are accepted as
+% values. The underlying code to ensure the requirements (as far as they
+% can be ensured) is incomplete, but a color profile is included and the
+% /OutputIntent is set. More information can be found in the documentation
+% of \pkg{l3pdfmeta}.
+% \item[\texttt{colorprofiles}] This allows to load icc-colorprofiles. Details
+% are described in the documentation of \pkg{l3pdfmeta}.
+% \item[\texttt{pdfmanagement}] Boolean. This activates/deactivates
+% the core management code. By default the value is true.
+% \item[firstaidoff] This accepts a comma lists of keysword and disable the patches
+% related to them. More information can be found in the documentation of
+% \pkg{pdfmanagement-firstaid}.
+% \end{description}
+%
+% \subsection{Container for document properties}
+%
+% The module provides a container where classes, packages and users can store
+% properties of the document which are perhaps of interest
+% or use for other packages or the author.
+%
+% The properties are stored with a key |label/property|. The values can be
+% retrieved expandably.
+%
+% \begin{function}{\AddToDocumentProperties}
+% \begin{syntax}
+% \cs{AddToDocumentProperties}\oarg{label}\Arg{property}\Arg{value}
+% \end{syntax}
+% This stores \meta{value} under the key \meta{label}/\meta{property}.
+% By default \meta{label} is the current package name |\@currname|. If another
+% label is choosen, it should be one which avoids clashes with other packages
+% using the container. The label |document| is reserved.
+% \end{function}
+%
+% \begin{function}{\GetDocumentProperties}
+% \begin{syntax}
+% \cs{AddToDocumentProperties}\Arg{label/property}
+% \end{syntax}
+% Expands to the \meta{value} corresponding to \meta{label/property}
+% in the container. If \meta{label/property} is missing,
+% this has an empty expansion.
+% The result is returned within \cs{exp_not:n}, which means
+% that the \meta{value} does not expand further
+% when appearing in an x-type argument expansion.
+% \end{function}
+%
+% \begin{function}{\ShowDocumentProperties}
+% \begin{syntax}
+% \cs{ShowDocumentProperties}
+% \end{syntax}
+% This show the current content of the container.
+% \end{function}
+%
+% \end{documentation}
+%
+% \begin{implementation}
+%
+% \section{\pkg{ltdocinit} implementation}
+% \subsection{\cs{DeclareDocumentMetadata}}

+% \cs{DeclareDocumentMetadata} should for now not be used after
+% \cs{documentclass} so we error in this case. It can be used more than once
+% but follow-up calls should not do the initialization code.
+% \begin{macrocode}

+% The wanted backend must be detected first, we read the init key and then
+% force the loading by either loading l3pdf (+ expl3) or only expl3.
+% \begin{macrocode}

+ %should be loaded after the backend is set, and only if not in the kernel
+ \cs_if_free:NTF \pdf_uncompress:

+% \end{macrocode}
+% Now we load the extra backend code and set the boolean to true
+% \begin{macrocode}
+ \ExplSyntaxOn\makeatletter
+ \file_input:n {l3backend-testphase-\c_sys_backend_str.def}
+ \ExplSyntaxOff\makeatother
+ \bool_gset_true:N \g_@@_active_bool
+% \end{macrocode}
+% set the default language, process the rest of the keys,
+% and setup the generic driver
+% \begin{macrocode}

+ \bool_if:NT \g_@@_active_bool
+ {

+ }
+% \end{macrocode}
+% \cs{pdfmanagement_add:nnn} has collected values in this hook.
+% \begin{macrocode}
+ \hook_use_once:n {pdfmanagement/add}
+% \end{macrocode}
+% Redefine \cs{DeclareDocumentMetadata} so that it only process the keys.
+% We need to update the hyperref option if the active status changes.

+% This code is temporary! It tries to patch commands of other packages or even
+% replace package which are incompatible with the pdfmanagement,
+% to remove clashes and test if everything works as expected.
+% This code should disappear when packages adapt to the central interfaces.
+%
+% The package contains an number of sections for various packages. Every
+% section can be disabled in (the first) \cs{DeclareDocumentMetadata} with
+% |firstaidoff={name1,name2,...}|.

+% internal \pkg{color} commands, so
+% that colors defined with its \cs{definecolor} command are known to \pkg{l3color} and
+% so \pkg{hyperref}. This only supports the color models from l3color (which covers
+% all standard model of the \pkg{color} package). The |named| model is mapped to
+% \cs{color_set:nn}.
+%
+% This patch serves also as test to check if this change can be safely
+% added to \pkg{color} later.

+% \pkg{l3color} to set the colors. It is therefore necessary to patch \pkg{xcolor}, so
+% that colors defined with its \cs{definecolor} command are known to \pkg{l3color} and
+% so \pkg{hyperref}. This only supports the color model from l3color. Colors defined

+% \subsection{\pkg{pgf}}
+%
+% In \pkg{pgf}, resource management is set up in the file |pgfutil-common.tex|.
+% This then provides three functions for adding to the resources, all of which
+% are objects:
+% \begin{itemize}
+% \item \cs{pgfutil@addpdfresource@extgs}: Extended graphics state
+% \item \cs{pgfutil@addpdfresource@colorspaces}: Color spaces
+% \item \cs{pgfutil@addpdfresource@patterns}: Patterns
+% \end{itemize}
+%
+% These resource dictionaries are used by adding entries in a cumulative sense;
+% the macro layer deals with ensuring that each entry is only given once. Note
+% that the objects themselves must be given only once for each page.
+%
+% To support these functions, there are a series of set-up macros which install
+% these resources. That has to take place for every page: the exact route
+% therefore depends on the driver.
+%
+% For the pdfmanagement project we need to avoid that pgf interferes in ExtGState,
+% ColorSpace and Pattern (Shadings are added to the xform resources and so probably
+% unproblematic for now).
+% The actual patch is in a file hook guarded by the boolean,
+% the rest of the code is always defined.

+% {\em This is a temporary package created to allow the manual
+% loading of the new \LaTeX{} PDF management code during a test phase.
+% It will disappear when the code is integrated into the \LaTeX{} format.}
+%
+% \medskip
+% \noindent During the test phase the package should be used like this:
+%
+% \begin{verbatim}
+% \RequirePackage{pdfmanagement-testphase} % load the package
+%
+% \DeclareDocumentMetadata % activate the PDF management (with options)
+% {
+% % options
+% }
+%
+% \documentclass {...}
+% \end{verbatim}
+% Note that the activation has to happen before the \cs{documentclass} declaration.
+% Because of this, the package needs loading with \cs{RequirePackage}.
+%
+%
+%
+% \section*{Feedback wanted!}
+%
+% Bug reports and feedback are welcome. Please open an issue at
+% \url{https://github.com/latex3/pdfresources}.
+%
+% While the code targets PDF as output format, feedback about the
+% effect on other formats is needed too.
+%
+% \section{Introduction}
+% The \LaTeX{} format currently contains nearly no code specific to the now quite
+% central output format, PDF. It also offers nearly no interfaces to important PDF related
+% primitive commands for package writers.
+%
+% Important tasks like supporting PDF standards,
+% creating links, adding special colors, managing the content of
+% central PDF-directories or even simple tasks like setting the PDF version
+% are delegated to external packages which have to recourse to
+% the primitive low-level commands in their code.
+%
+% This is problematic for three reasons:
+% \begin{itemize}
+%\item At first using primitives directly can lead to clashes and duplicate
+% settings with conflicting values---nothing prevent packages to add for example
+% the \texttt{/Title} twice to the Info dictionary, the \texttt{/Lang} entry
+% twice to the Catalog, or to add two \texttt{/ExtGState}
+% resources to a page. The PDF normally doesn't break in such
+% cases---the format is quite robust---but it will ignore one of the duplicates and
+% the output can be wrong.
+%
+% \item At second the primitives differ between the various engines and backends with
+% which \LaTeX{} is used. To support the engines and backend
+% packages have to write and maintain
+% \enquote{driver} files which they did to a varying degree. This makes it
+% difficult for users to assess if a package will work with their work-flow and
+% is a strain for package writers as they have to keep track of engine and backend changes.
+%
+% \item And at last generic hooks and configuration points to various
+% PDF related structures are missing and difficult to add.
+% \end{itemize}
+%
+% Despite the potential problems, until now the number of conflicts were
+% small and could be resolved in an ad-hoc fashion. But the future plans for
+% \LaTeX{} regarding support for tagged PDF and
+% PDF standards mean that much more PDF specific code will have to be
+% written by the kernel directly and this can not be done without proper,
+% well-defined and well-behaving interfaces and hooks.
+%
+% Some first steps for better support of PDF related commands have been already done
+% with the \pkg{l3pdf} package which has now been integrated into \pkg{l3kernel}.
+% It offers backend independent commands to create
+% PDF objects and destination, to set the compress level and the PDF version.
+%
+% The PDF management bundle extends this to more PDF related areas
+% and provides interfaces to them in a backend independent way.
+%
+% The new PDF management has three main objectives
+% connected with the problems identified above:
+% \begin{itemize}
+% \item For commands with \enquote{clash potential} it implements commands to
+% replace the primitives and so to resolve potential conflicts.
+%
+% \item It implements commands for a variety of PDF related tasks
+% and supports a well-defined set of backends.
+%
+% \item If sensible this commands are enhanced by hooks from the new
+% \LaTeX{} hook system. This has been e.g.\ done for annotations in the
+% \pkg{l3pdfannot} bundle.
+% \end{itemize}
+%
+% \section{\enquote{Change Strategy}: The integration into \LaTeX\label{sec:change}}
+%
+% The central module of this bundle, \pkg{l3pdfmanagement}, defines an interface
+% for the (pdf\TeX) primitives \cs{pdfcatalog}, \cs{pdfinfo},
+% \cs{pdfpagesattr}, \cs{pdfpagesattr} and \cs{pdfpageresources} and
+% the analog commands from the other engines and backends.
+%
+% All these commands have a \enquote{clash potential}, this means that the new
+% interface is incompatible with a parallel use of the primitive commands
+% which it targets to replace and supersede.
+% This doesn't affect many packages, but the list of package using such primitives
+% contains central and important packages like \pkg{hyperref}, \pkg{tikz},
+% \pkg{pdfx} and more.
+%
+% So while the goal is to integrate the code into the \LaTeX{} format directly,
+% this can not be done immediately without conflicts with existing documents and packages.
+%
+% As an intermediary step the package \pkg{pdfmanagement-testphase} has been
+% created which loads the code manually.
+% With it package authors and users can test the new code, give feedback
+% and packages can be adapted.
+%
+% Loading the package will only \emph{load} the modules,
+% to \emph{activate} the core PDF management the trigger command
+% \cs{DeclareDocumentMetadata} has to be used too.
+% The loading and activation has to be done
+% \emph{before} the \cs{documentclass} command.
+%
+%
+% We hope that this setup will allow packages writers and users to test the
+% PDF management code and adapt packages and documents safely.
+%
+%
+% \section{Backend support}
+% The supported backends are pdflatex, lualatex, (x)dvipdfmx (latex, xelatex,
+% dvilualatex (in texlive 2021))
+% and dvips with ps2pdf (not completely yet). dvips with distiller could work too
+% but is untested.
+%
+% That the interfaces and commands are backend independent doesn't mean
+% that the results and even the compilation behavior is identical.
+% The backends are too different to allow this.
+% Some backends expand arguments e.g. in a \cs{special} while other don't.
+% Some backends can insert a resource at the first compilation, while another uses
+% the aux-file and a label and so needs at least two compilation runs.
+% Some backends manage some of the resources through side-effects,
+% some manage them automatically.
+% All this mean that package writers will still have to keep an eye on
+% backend requirements and run tests for all variants. Also backend specific code
+% will still be needed in some cases.
+%
+% \section{Use}\label{sec:use}
+% The package should be loaded before \cs{documentclass}. To activate
+% the resource management it should be followed by
+% \cs{DeclareDocumentMetadata}\marg{key-val}.
+% The options of \cs{DeclareDocumentMetadata} are described in the documentation of
+% \pkg{ltdocinit}.
+%
+% \begin{verbatim}
+% \RequirePackage{pdfmanagement-testphase} % load the package
+% \DeclareDocumentMetadata % activates the PDF management interface
+% {
+% %options
+% }
+% \documentclass {...}
+% \end{verbatim}
+%
+% The PDF management can be deactivated either setting the key
+% \texttt{pdfmanagement} to \texttt{false} or by commenting out
+% the whole \cs{DeclareDocumentMetadata} declaration.
+%
+% To test if the PDF management is active the predicate
+% \cs{pdfmanagement_if_active:TF} can be used, see the documentation of \pkg{l3pdfmanagement}.
+%
+% \section{Requirements}
+% The new PDF management requires a \LaTeX{} format from 2020/10/01 or later
+% and an L3 programming layer of 2021-02-18 or later.
+% It currently depends on the experimental packages \pkg{l3ref-tmp} and \pkg{l3bitset}.
+% In some places, e.g. when writing strings to the pdf it assumes that
+% the file is utf8 encoded -- ascii will naturally work too, but legacy 8bit encodings are
+% not supported.
+%
+% \section{Modules}
+% The bundle contains a number of modules. The majority of the modules don't
+% have a stand alone \texttt{sty}, their code is combined
+% in one file and loaded by the main package. The organization and naming is bound
+% to change over time: For almost all modules the goal is to
+% integrate them into the format and the individual files to disappear.
+%
+% The description items give the name of the documentation
+% of the modules. There doesn't exist in all cases a related |.sty|.
+%
+% \begin{description}
+% \item[l3pdfdict] This module provides commands for PDF dictionaries. Its main
+% purpose is to create name spaces. The code used e.g. by \pkg{l3pdfmanagement} and
+% \pkg{l3pdfannot}.
+%

+% \section{Incompabilities}
+%
+% As described in section~\ref{sec:change}, if activated
+% the new PDF management takes over the management of core PDF dictionaries.
+% All packages
+% that bypass the PDF management and access these dictionaries with primitives like
+% \cs{pdfcatalog}, \cs{pdfinfo}, \cs{pdfpageresources}, \cs{pdfpagesattr}
+% and \cs{pdfpageattr} or similar commands from other engines and backends are
+% basically incompatible: values can get lost or will be wrong.
+%
+% The following describes known incompatible packages along with some suggestions
+% how this should or will be handled in future. The list is not exhaustive.
+%
+% \subsection{hyperref}
+% A generic driver that can
+% be used as replacement has been developed and is provided by this bundle.
+% It will be loaded automatically if the pdf management is active.
+%
+% The generic driver differs in some points from other \pkg{hyperref} drivers:
+% \begin{itemize}
+% \item The code for bookmarks has been removed from this driver, instead
+% the \pkg{bookmarks} is loaded and used.
+% \item The driver isn't yet fully integrated into hyperref. This means that
+% it doesn't react to a number of package options. Instead \cs{hypersetup} should
+% be used.
+% \item Incomplete is the support for form fields. Quite probably form fields will
+% be extracted in a dedicated package.
+% \item The driver uses for the color handling the l3color package. While normally
+% it should be able to use colors defined with color and xcolor, there could be
+% edge cases where it fails.
+% \item The colors have been changed (this counts probably as an improvement \ldots).
+% \end{itemize}
+%
+% More details can be found in the documentation \pkg{hyperref-generic.pdf}.
+%
+% \subsection{pdfx}
+% \pkg{pdfx} is not compatible. It uses the commands \cs{pdfpagesattr}, \cs{pdfpageattr},
+% \cs{pdfinfo} and \cs{pdfcatalog}. The needed changes are not many, but can
+% not be done by external patches.
+%
+% It is also one goal of the pdfmanagement project to
+% offer support for standards natively. The code is under development,
+% see the documentation of \pkg{l3pdfmeta}.
+%
+% \subsection{hyperxmp}
+% \pkg{hyperxmp} uses \cs{pdfcatalog} to insert the \texttt{/MetaData} reference. This
+% makes it incompatible, but adjusting this is even possible with external
+% patches. \pkg{hyperxmp} also relies on some \pkg{hyperref} internals, so
+% changes in \pkg{hyperref} must be coordinated.
+%
+% Some patch code is provided by the bundle and loaded automatically,
+% but it is not complete currently. Failures are e.g. possible with complicated
+% author or title settings. The handling of dates isn't correct either yet.
+% The patch code can be disabled by using |firstaidoff=hyperxmp| in \cs{DeclareDocumentMetadata}
+%
+% \subsection{tikz/pgf}
+% \pkg{pgf} writes to the page resources too and so is incompatible. The needed
+% changes are rather small and will be done in coordination with the maintainer.
+% Until this works, \pkg{pagemanagement} will load the patches automatically.
+% This can be disabled by using |firstaidoff=pgf| in \cs{DeclareDocumentMetadata}
+%
+% \subsection{transparent}
+% The package \pkg{transparent} is incompatible. A replacement has been written
+% (\pkg{transparent-ltx}) and is loaded automatically. It requires a very recent
+% L3 programming layer!
+% This can be disabled by using |firstaidoff=transparent| in \cs{DeclareDocumentMetadata}
+% \subsection{pdflscape}
+% The package \pkg{pdflscape} is incompatible. A replacement has been written
+% (\pkg{pdflscape-ltx}) and is loaded automatically.
+% This can be disabled by using |firstaidoff=pdflscape| in \cs{DeclareDocumentMetadata}
+%
+% \subsection{colorspace}
+% The package is incompatible. Some patches
+% have been added to \pkg{pdfmanagement-firstaid}.
+% Alternative code for spot colors is
+% in the \pkg{l3color} package which has now been add to \pkg{l3kernel}.
+%
+% \subsection{embedfile, attachfile, attachfile2}
+% Tools needed to be able to write a replacement
+% to replace these packages have been developed in the \pkg{l3pdffile} package.
+% Full replacements for the packages don't exist yet.
+%
+% \subsection{tagpdf}
+% The development code is compatible and will be uploaded in time.
+%
+% \subsection{ocgx2, animate, media9}
+% These package all make use of low-level PDF command and will
+% have to be reviewed.
+%
+% \subsection{acrotex}
+% The \pkg{acrotex} makes heavy use of PDF commands and so must be reviewed and
+% adapted, including the currently untested route dvips + distiller.
+%
+% \subsection{fancytooltips}
+% This package uses \cs{pdfpageattr} and \pkg{acrotex} and so must be reviewed.
