I can use the special package handling like for arydshln in the EmbeddedObjects manual. Then the document would always be compilable, but you won't see sec. 20 in the output. Should I do this?
Of course I have to do this since mhchem is not in the standard/basic installation of TeXLive nor MiKTeX.
I've done this now, please test if the Math manual is now compilable. thanks and regards Uwe
