% \section{Introduction}
%
%    This code implements small files which can be loaded with the |testphase|
%    key of \cs{DocumentMetadata}. This will be extended to allow user to load
%    well defined parts of the tagged PDF project.
%    Currently the values |phase-I|, |phase-II| and |new-or| are provided.
%    |tagpdf| is an undocumented alias for |phase-II| which is kept for compability.

% \section{The Implementation}
%  New output routine code is loaded in phase-II and new-or:
%    \begin{macrocode}
%<*tagpdf|phase-II|new-or>
\IfFileExists{latex-lab-testphase-new-or.sty}
 {
   \RequirePackage{latex-lab-testphase-new-or}
 }
 {}
%</tagpdf|phase-II|new-or>
%    \end{macrocode}
%    \begin{macrocode}
%<*tagpdf|phase-I|phase-II>
%    \end{macrocode}
%
%    \begin{macrocode}
\RequirePackage{tagpdf}
\AddToDocumentProperties [document]{testphase/tagpdf}{loaded}
%</tagpdf|phase-I|phase-II>
%<tagpdf|phase-II>\tagpdfsetup{activate,paratagging,interwordspace}
