Actually I don’t want that much Texinfo in a Scheme file, and I don’t
want the automatically-generated “Usage” subsection.
Besides, I initially started by just putting address@hidden sxml-match.texi’

Thanks for the hints, I’ll try to look into it.
I note that you subtly omitted to comment on the issue above. :-)
