Isn't this a recursive defintion? You are saying that "RDF schema is for RDF
vocabulaires" and that "XML Schema is for XML documents" ??

Anyway, my feelings are that for many (meta)data communities, they will 
need both schema languages. RDF Schema to establish the relationships
between
properties and XML Schema for validating (meta)data instances.
