Specifying the schema as a grammar makes things quite difficult for
developing a Schematron schema for RDF. (I have tried to create another one,
b.t.w. for the new syntax: things seems a lot clearer than the old)  Because 
one has to look at the new "grammar" and try to guess what
the intent of the productions are supposed to be.

Which is a shame, because RDF clearly has the kinds of patterns that
Schematron can express. And things like rdf:_1  (which otherwise doom RDF
to unmaintainability) should pose no problems either.
