You could put the documentation in the module commentary of (sxml
match), as texinfo. Or you could extend module-commentary somehow to
look for commentaries in other sources. Probably easiest just to paste
the texinfo you already wrote into the commentary, no?

It would certainly be possible to maintain a stack of source locations
in the expander, and modify syntax-violation to look in that stack.
There is also the possibility of simply inspecting the syntax objects
given to syntax-violation for source info, but it might not be there --
best to have a stack to at least give approximate info.
