My proposed XML Schema/RDF Schema/RDF integration is showing in the examples
I sent an hour ago:

http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2001Nov/0198.html

Basically the XML Schema sits in one file, and the RDF or RDFS refers to it
in some way (e.g. using its URL or using xsi:schemaLocation).

In this framework RDFS *does not* duplicate any of the mechanisms of XML
Schema but merely uses them (in external XML Schema files).

This is me trying to play by the charter; we might want to conclude that
this is sufficiently messy that the charter should be interpreted more
liberally.
