+% This key can be used in \cs{tagpdfsetup} to declare and rolemap new tags.

+% The key-value list knows the following keys:

+% \item[\texttt{namespace}] This is the namespace of the new type.
+%   The value should be a shorthand of a namespace.
+%   The allowed values are currently |pdf|, |pdf2|, |mathml| and |user|.
+%   The default value (and recommended value for a new tag) is |user|.
+%   The public name of the user namespace is |tag/NS/user|. This can be used to reference
+%   the namespace e.g. in attributes.
+% \item[\texttt{role}] This is the type the tag should be mapped too.
+%  In a PDF 1.7 or earlier this is normally a type from the |pdf| set,
+%  in PDF 2.0 from the |pdf|, |pdf2| and |mathml| set.
+%  It can also be a user type, or a still unknown type.
+%  The PDF format allows mapping to be done transitively.
+%  But tagpdf can't/won't check such unusual role mapping.
+% \item[\texttt{role-namespace}] If the role is a known type
+%  the default value is the default namespace of this type.
+%  If the role is unknown, |user| is used and
+%  the code hopes that the type will be defined later. With this key a specific

+Beside this mostly some clean up and bug fixes has been done.

+A more important step will be done in \LaTeX{} itself in the next dev-release: The command \cs{DocumentMetadata} will be
+added to the format and will take over the role of \cs{DeclareDocumentMetadata} from \pkg{pdfmanagement-testphase} and additionally
+will also load the pdf management code. This will simplify the documents as it will no longer be needed to load

 \subsection{Proof of concept: the tagging of the documentation itself}
 
 Starting with version 0.6 the documentation itself has been tagged. The tagging wasn't (and isn't) in no way perfect. The validator from Adobe didn't complain, but PAX3 wanted alternative text for all links (no idea why) and so I put everywhere simple text like \enquote{link} and \enquote{ref}. The links to footnotes gave warnings, so I disabled them. I used types from the \PDF{} version 1.7, mostly as I have no idea what should be used for code in 2.0. Margin notes were simply wrong \ldots

+\section{Structure destinations}\label{sec:struct-dest}
+
+ Standard destinations (anchors for internal links)
+ consist of a reference to a page in the pdf and instructions
+ how to display it---typically they will put a specific coordinate in the left top corner
+ of the viewer and so give the impression that a link jumped to the word in this place.
+ But in reality they are not connected to the content.
+
+ Starting with pdf~2.0 destinations can in a tagged PDF also point
+ to a structure (to a \texttt{/StructElem} object).
+ GoTo links can then additionally to the \texttt{/D} key which points to a
+ standard page destination also point to such a structure destination with an \texttt{/SD} key.
+ Programs that e.g. convert such a PDF to html can then create better links.
+ (According to the reference, PDF-viewer should prefer the structure destination
+ over the page destination, but as far as it is known this isn't done yet.)
+
+ Currently structure destinations (and GoTo links making use of it) could natively only
+ be created with the dvipdfmx backend. With pdftex and lualatex it was only possible to create
+ a restricted type which used only the \enquote{Fit} mode. Starting with
+ \TeX{}live 2022  (earlier in miktex) both engines will knew new keywords which allow
+ to create structure destination easily.
+
+ Support for this has been already added to the pdfmanagement and \pkg{tagpdf} will make
+ use of it if possible. In most cases it should simply work, but one should be aware
+ that as one now has a destination that is actually tied to the content it gets more
+ important to actually consider the context and the place where such destinations
+ are created. It now makes a difference if the destination is created before the
+ structure is opened or after so in some cases
+ code that place destinations should be changed to place them inside the structure they
+ belong too. .
+ One also has to consider the pages connected to the destinations: The structure destination
+ is bound to the page where the structure \emph{begins}, if this differ from the page of the page destination
+ (e.g. if the destination is created by a \verb+\phantomsection+  in the middle of a longer paragraph)
+ then be necessary to surround
+ destinations with a dummy structure (a Span or an Artifact) to
+ get the right page number.
