When thinking about implementing something I read the spec.

Well if it really don't requires xslt/exslt then that would be doable. > The implementation is fairly trivial, and there are existing > implementations in XSLT: It looks simple, problably the reason why I didn't understood the spec :-) > http://xml.ascc.net/schematron/1.5/ > > I've used some of the sample metastylesheets with xsltproc, and have had > no problems.

If it's short, blessed by ISO, sensible and amount to less than 1000 lines of C and 20KB of code I wouldn't mind getting it added to libxml2.
