+% It must be possible to suppress both the collecting and the tagging of math. 
+% Currently both tasks are still connected and controlled by the boolean
+% \cs{l_@@_collected_bool} so we define only commands for the tagging case.
+% As these will probably be needed in more than one place in the
+% testphase we check for existence. 
+% TODO: At the end they should move to tagpdf.
