currently (as of libxml2 2.6.29), the schematron implementation writes validation error messages to stderr with a plain fprintf in xmlSchematronReportOutput (happily annotated with a "TODO").

However, to make schematron usable in lxml, I need a way to propagate these errors to the Python level. I would therefore like to see them passed into __xmlRaiseError().

The schematron code is really not complete, that sure could be fixed but a lot more may be needed. I asked for a definitive set of test for the ISO version and never got an answer, so I got discouraged and dropped working on it at the time. Of course now I have far less time for libxml2

Ah, that's too bad. Can you comment on how complete you consider the current Schematron implementation? Stefan
