+% underscore can not be used in label and references unless the package option \texttt{strings} is used
+% (which patches a selection of problematic commands like \cs{label} and \cs{ref})

+% a selection of problematic commands like \cs{@testdef} or \cs{@newl@bel}.

+% One of the main problems is how to properly embed them in the

+% \begin{abstract}
+% The following code implements a first draft for the tagging of
+% tables. It still has a large number of limitations and restrictions!
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{Documentation}
+%
+% In \LaTeX{} the word \texttt{table} is used as the name of the float environment that can contain
+% a data table\footnote{But it does not really have to, you can put
+% other material into such environments.} along with a caption and some additional text. The environments for
+% actual data tables have various names like \texttt{tabular}, \texttt{tabular*},
+% \texttt{tabularx} and \texttt{longtable}---the last should not be used inside a float
+% and supports its own caption command.
+%
+% In this documentation \enquote{table} always means such data tables and not the float
+% environment.
+%
+% Tagging of tables is on one side doesn't look very difficult: one only has to
+% surround rows and cells by TR and TH or TD structures.
+% But there are difficulties:
+% \begin{itemize}
+% \item
+% One is that over the years various packages related to tables have
+% been written that all change some of the internals. Inserting the
+% tagging commands and testing all the variants and various nestings
+% is not trivial.
+%
+% \item
+% The other difficulty is that most of the existing environments to
+% create tables do not know the concept of headers as a semantic
+% structures.
+%
+% \item
+% Headers are only produced through visual formatting, e.g., by
+% making them bold or by underlying some color. But accessible
+% tables need headers (and the PDF/UA standards requires them) and
+% this means that additional syntax to declare headers (when they
+% can't be guessed) must be developed. This is still an area for
+% research.
+% \end{itemize}
+%
+% Right now, this module therefore does implement only some basic
+% support for the tagging of tables. A list of the known limitations
+% is shown below.
+%
+% The module is not loaded automatically (i.e., not yet integrated
+% into any \texttt{phase-XX}) and by itself it doesn't activate
+% tagging. For experimenting with table tagging it is therefore best
+% to load it in combination
+% with phase-III in \cs{DocumentMetadata}, i.e.:
+%
+% \begin{verbatim}
+% \DocumentMetadata{testphase={phase-III,table}}
+% \end{verbatim}
+%
+% It will then automatically tag all table environments it already supports with
+% the exception of tables in the header and footer of the page (where tagging is disabled).
+% Such tables can be nested.
+%
+% If a table should not be tagged as table, for example because it is merely used
+% to produce a layout or because it is a not yet (fully) supported table structure,
+% the tagging can be disabled with
+% \verb|\tagpdfsetup{table-tagging=false}|.
+%
+% Inside cells the automatic tagging of paragraphs is disabled with the exception of
+% p/m/b-type cells.
+%
+% Rows do not need to contain a full number of \&, missing cells are automatically
+% added with an empty TD-structure.
+%
+% There is some basic support\footnote{This is not meant to be the
+% final interface, though.} for headers. With
+% \begin{quote}
+% \verb|\tagpdfsetup{table-header-rows={|\meta{list of row numbers}\verb|}|
+% \end{quote}
+% you can
+% declare which (absolute) row numbers should be tagged as header rows.
+% It applies to all tables until it is changed to a different list of row numbers or undone by setting
+% the key to \meta{empty}.
+% A row number can be
+% negative, then the counting starts from the end of the table. There is no support
+% for header columns yet. In a \env{longtable} the code will currently use the \cs{endhead} or
+% \cs{endfirsthead} rows as header if one of these commands has been
+% used and in that case the code
+% ignores a \texttt{table-header-rows} setting.
+%
+% You should not insert meaningful text with \verb+!{...}+ or \verb+@{...}+ or \cs{noalign}
+% between the rows or columns of the table.
+% With pdflatex such text will be unmarked, with lualatex it will be marked as artifact.
+% Either case means that it will be currently ignored in the
+% structure.\footnote{While it is theoretically possible
+% to collect such text and move it into a structure it would require manual markup
+% from the author to clarify where this text belongs too.}
+%
+% As mentioned below the \pkg{colortbl} doesn't yet work properly with the tagging,
+% but once it does, then colors inside the table will probably be
+% simply ignored (at least initially). If such a color
+% has a semantic meaning (like \enquote{important value}) this meaning will be lost.
+%
+% Feedback and problems with the code can be reported at
+% \url{https://github.com/latex3/tagging-project} either in form of
+% explicit issues or as a \enquote{discussion topic}, whatever works best.
+%
+%
+% \section{Limitations}
+%
+% \begin{itemize}
+% \item The code loads the \pkg{array} package and so does not work without it (that is
+% not really a limitation, but can affect existing tables).
+%
+% \item It supports only a restricted number of tables types. Currently
+% \env{tabular}, \env{tabular*}, \env{tabularx}, and \env{longtable}.
+%
+% \item the \env{array} environment is assumed to be part of math and tagging as a table is disabled for
+% it.
+%
+% \item Row spans are not yet supported (and the \pkg{multirow} package is untested).
+%
+% \item The \pkg{colortbl} package breaks tagging if there are nested tables. It also breaks
+% the filling up of incomplete rows.
+%
+% \item The \pkg{tabularray} package use a completed different
+% method to create tables and will not be supported by this code.
+%
+% \item The \pkg{nicematrix} package is currently incompatible.
+%
+% \item Most other packages related to tables in \LaTeX{} are not yet tested,
+% that includes packages that change rules like \pkg{booktabs}, \pkg{hhline},
+% \pkg{arydshln}, \pkg{hvdashln}.
+%
+% \item \env{longtable} currently only works with lualatex.
+% With other engines it breaks as its output
+% routine clashes with the code which closes open MC-chunks at pagebreaks and
+% if this is resolved there will probably be problems with the head and foot boxes
+% (but this can't be tested currently).
+%
+% \item Not every table should be tagged as a Table structure, often they are
+% only used as layout help, e.g. to align authors in a title pages. In such uses
+% the tagging of the table must be deactivated with \verb|\tagpdfsetup{table-tagging=false}|.
+%
+% \item Only simple header rows are currently supported. Columns and complex headers with
+% subheaders will be handled later as that needs some syntax changes. Tables
+% with more than one header row are probably not pdf/UA as the headers array in
+% the cells is missing.
+%
+% \item A \pkg{longtable} \cs{caption} is currently simply formatted as a multicolumn and
+% not tagged as a \texttt{Caption} structure.
+%
+% \item The \pkg{caption} package will quite probably break the \pkg{longtable} caption.
+%
+% \item The setup for \pkg{longtable} requires lots of patches to internal \pkg{longtable}
+% commands and so can easily break if other packages try to patch \pkg{longtable} too.
+%
+% \item The \env{longtable} environment supports footnotes in p-type columns, but it hasn't been
+% tested yet if this works also with the tagging code.
+%
+% \item The code is quite noisy and fills the log with lots of
+% messages.\footnote{Helpful for us at this stage.}

+% \section{Introduction}
+%
+%
+% \section{Technical details and problems}
+%
+% The implementation has to take care of various details.
+%
+% \subsection{TODOs}
+%
+% \begin{itemize}
+% \item
+% Test \texttt{array-006-longtable.lvt} and
+% \texttt{array-007-longtable.lvt} have errors with pdftex (para
+% tagging)
+%
+% \item
+% Instead of before/after hooks we should add sockets directly
+% into the code.
+%
+% \item Debugging code and messages must be improved.
+%
+% \item Cells need an \texttt{Headers} array.
+%
+% \item Row spans should be supported (but perhaps need syntax support)
+%
+% \item Longtable captions should be properly supported.
+%
+% \item Handle p-cells better. para-tagging should probably be enabled,
+% but Part can't be a child of TD, so this should probably be changed to Div here.
+% Also there is a stray MC somewhere.
+%
+% \item More packages must be tested.

+% \begin{macrocode}
+\ProvidesExplPackage {latex-lab-testphase-table} {\ltlabtbldate} {\ltlabtblversion}
+ {Code related to the tagging of tables}
+% \end{macrocode}
+% This builds on \pkg{array} so we load it by default:

+\RequirePackage{array}
+% \end{macrocode}
+%
+%
+% \subsection{Variables}
+% \begin{macro}
+% {
+% \l_@@_celltag_tl

+% ,\l_@@_cellattribute_tl
+% ,\l_@@_rowattribute_tl
+% ,\g_@@_missingcells_int
+% ,\l_@@_tmpa_clist
+% ,\l_@@_tmpa_seq
+% ,\l_@@_tmpa_tl
+% }
+% This is for the celltag, e.g. TD or TH:
+% \begin{macrocode}
+\tl_new:N \l_@@_celltag_tl
+\tl_set:Nn \l_@@_celltag_tl {TD}
+% \end{macrocode}
+% For the rowtag, probably always TR:
+% \begin{macrocode}
+\tl_new:N \l_@@_rowtag_tl
+\tl_set:Nn \l_@@_rowtag_tl {TR}

+\tl_set:Nn \l_@@_cellattribute_tl {}
+\tl_new:N \l_@@_rowattribute_tl

+\tl_new:N \l_@@_tmpa_tl
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{Sockets}
+%
+% The code uses a number of sockets to inject the tagging
+% commands. These can be easily set to a noop-plug in case the
+% automated tagging is not wanted At first sockets for the begin and
+% end of cells and rows
+%
+% \begin{socketdecl}{tagsupport/tblcell/begin,
+% tagsupport/tblcell/end,
+% tagsupport/tblrow/begin,
+% tagsupport/tblrow/end,
+% }
+% \begin{macrocode}
+\NewSocket{tagsupport/tblcell/begin}{0}
+\NewSocket{tagsupport/tblcell/end}{0}
+\NewSocket{tagsupport/tblrow/begin}{0}
+\NewSocket{tagsupport/tblrow/end}{0}
+% \end{macrocode}
+% \end{socketdecl}
+%
+% \begin{socketdecl}{tagsupport/tbl/init}
+% This socket should be at the begin of the table, inside a group.
+% It is meant for settings like disabling paratagging. This socket
+% can perhaps be merged later into the begin-sockets when they are
+% no longer added as hooks but in the environment definitions.
+% \begin{macrocode}
+\NewSocket{tagsupport/tbl/init}{0}
+% \end{macrocode}
+% \end{socketdecl}
+%
+%
+% \begin{socketdecl}{tagsupport/tbl/finalize}
+% To fine tune the structure (change cells to header cells, remove
+% unwanted structures, move a foot to the end, etc.) we also need a
+% socket that is executed at the end of the table but \emph{before}
+% all the variables are restored to the outer or default values.
+% The code in the socket can make assignments, but probably
+% shouldn't do typesetting and not write whatsits.
+% \begin{macrocode}
+\NewSocket{tagsupport/tbl/finalize}{0}
+% \end{macrocode}
+% \end{socketdecl}
+%
+% \begin{socketdecl}{tagsupport/tbl/finalize/longtable}
+% \env{longtable} needs its own socket to fine tune the structure.
+% Simply switching the plug in the previous socket interferes with
+% enabling/disabling the tagging.
+% \begin{macrocode}
+\NewSocket{tagsupport/tbl/finalize/longtable}{0}
+% \end{macrocode}
+% \end{socketdecl}
+%
+% \begin{socketdecl}{tagsupport/tblhmode/begin,
+% tagsupport/tblhmode/end,
+% tagsupport/tblvmode/begin,
+% tagsupport/tblvmode/end
+% }
+%
+% These sockets are used in the begin and end code of environments,
+% to allow a fast enabling and disabling of the tagging. We
+% distinguish between tables that can be used inside paragraphs and
+% standalone tables like longtable.
+% \begin{macrocode}
+\NewSocket{tagsupport/tblhmode/begin}{0}
+\NewSocket{tagsupport/tblhmode/end}{0}
+\NewSocket{tagsupport/tblvmode/begin}{0}

+% \end{macrocode}

+ \seq_gput_right:Ne \g_@@_struct_cur_seq { \tag_get:n {struct_num} }
+% \end{macrocode}
+% we store the cells of multicolumns as negative number. This allow to skip them
+% or to use them as needed.

+% \enquote{vmode} tables like longtable.
+%
+% \begin{plugdecl}{Table}
+% Inside a table we currently only disable paratagging. We assume

+% If neither \cs{endhead} nor \cs{endfirsthead} has been used

+ { \seq_if_empty_p:N \g_@@_LT@firsthead_rows_seq }
+ { \@@_set_header_rows: }
+% \end{macrocode}
+% Otherwise, if firsthead has not been used we use head. For this
+% we simple retrieve the row numbers and then call the header
+% command.
+% \begin{macrocode}

+ \@@_set_header_rows:
+% \end{macrocode}
+% Additionally we have to remove the head to avoid duplication. The

+% \subsubsection{Header support}
+%
+% Accessible table must have header cells declaring the meaning of the
+% data in a row or column. To allow a data cell to find it header cell(s)
+% a number of things must be done:
+% \begin{itemize}
+% \item every cell meant as a header should use the tag \texttt{TH}.
+%
+% \item header cells should have a \texttt{Scope} attribute with the
+% value \texttt{Column}, \texttt{Row} or \texttt{Both}. This is not
+% needed in the first row or column of a table.
+%
+% \item For more complex cases both \texttt{TD} and \texttt{TH} cell
+% can contain a \texttt{Headers} attribute, that is an array of
+% \texttt{ID}s of \texttt{TH} cell.
+% \end{itemize}
+%
+% For now we support only header rows.
+%
+% At first we define attributes for the three standard cases:
+% We delay to begin document
+% as we can't know if tagpdf is already loaded.
+% \begin{macrocode}
+\AddToHook{begindocument}
+ {
+ \tag_if_active:T
+ {
+ \tagpdfsetup
+ {
+ newattribute =
+ {TH-col}{/O /Table /Scope /Column},
+ newattribute =
+ {TH-row}{/O /Table /Scope /Row},
+ newattribute =
+ {TH-both}{/O /Table /Scope /Both},
+ }
+% \end{macrocode}
+%
+% And we put all three into the class map (perhaps the next tagpdf
+% should do that directly with newattribute):
+%
+% \begin{macrocode}
+ \seq_gput_left:Ne\g__tag_attr_class_used_seq
+ {\pdf_name_from_unicode_e:n{TH-col}}
+ \seq_gput_left:Ne\g__tag_attr_class_used_seq

+ \seq_gput_left:Ne\g__tag_attr_class_used_seq
+ {\pdf_name_from_unicode_e:n{TH-both}}
+ }
+ }
+
+% \end{macrocode}
+%
+% \begin{variable}{\l_@@_header_rows_clist}
+% This holds the numbers of the header rows. Negative numbers are
+% possible and count from the back.
+% \begin{macrocode}
+\clist_new:N \l_@@_header_rows_clist
+% \end{macrocode}
+% \end{variable}
+%
+% \begin{macro}{\@@_set_header_rows:}
+% TEMP: Next tagpdf will have the right command which also updates
+% the debug info.
+% For now a temporary command:

+% Longtable is complicated. When at the begin the \cs{endhead},
+% \cs{endfirsthead}, \cs{endfoot} and \cs{endlastfoot} are used to
+% setup head and foot they create each a structure subtree with one or
+% more rows. From this structures we want to keep at most two (head
+% and foot) and move the foot to the end of the table. When the head
+% and foot boxes are (re)inserted on following pages we want to mark
+% them up as artifact with the exception of the head at the begin and
+% the foot box at the end.
+%
+% TODO: When a line is killed the structure subtree is there already
+% too and must be removed.

+%
+% The structure of tocs consist of nested TOC and TOCI structures.
+% The code uses the first argument of the \cs{contentsline} command to detect the
+% level and to decided if a structure should be closed. The structure that
+% should be used in \texttt{/Ref} key to link to the heading is detected from the
+% target name in the fourth argument -- because of this with this code such a target
+% name is created and stored also if hyperref is not loaded.
+%
+% \subsection{Manual toc additions}
+% As the \texttt{/Ref} key relies on the target name,
+% manual \cs{addcontentsline} commands must ensure that they reference the right
+% structure. If an unnumbered heading command is used before this is normally the case,
+% so the following should work fine:
+%
+% \begin{verbatim}
+% \chapter*{Unnumbered}
+% \addcontentsline{toc}{chapter}{Unnumbered}
+% \end{verbatim}
+%
+% If there is no heading command a target name must be created manually \emph{inside the
+% right structure} with \cs{MakeLinkTarget}:
+%
+% \begin{verbatim}
+% \noindent % start e.g. P-structure
+% \MakeLinkTarget*{unnumbered}% target inside the P-structure
+% Unnumbered
