I disagree. XML Schema is about constraining the surface XML. RDF Schema is
about constraining triples (the relationship to XML Schema depends entirely
on the serialization syntax)

My view, as I have expressed before, is that RDF should not provide a
serialization syntax the way it currently does. It should provide:

	1. the triple model [done]
	2. a schema for constraining the model [done]
	3. a means for describing, in an XML schema, how instances of that
schema map to RDF triples
