So in summary you don't use an XML Schema becauase it puts too much
constraint on RSS: which doesn't need constraining to the degree of
asserting element ordering. However, you do want *some* structure, so you
use Schematron, correct? Also, you have an RDF Schema, like all good RDF
languages should - but only to assert the RDF aspects of RSS, not the
structure. So what this all boils down to is that some RDF specific
structuring may be needed (like Schematron. I suppose we could just use
Schematron), but on the whole RDF Schemas are the most important aspect....
