I agree that we should ship separate Schematron schema. I think that we 
can left Schematron rules inside RELAX NG because in some tools it works 
and some are just ignoring it. I didn't came across tool that will 
complain about current schema (no sch:pattern and sch:ns). But if there 
is such tool, we should definitively remove Schematron rules until this 
problem gets resolved.

Yep. Probably we should try to put together list of RELAX NG+Schematron 
implementations against we could test schemas. There are validators that 
I know:

MSV (+relames)
Topologi Schematron Validator
oXygen
Relaxed (product of my student, see http://badame.vse.cz/validator/)
