A big problem here is that QNames and URIs are not being used in a web
interoperable or meaningful way. Are you saying that the concept
"unsignedInt" as named by

http://www.w3.org/2000/10/XMLSchema#unsignedInt

is different than the concept "unsignedInt" as named by:

http://www.w3.org/2000/10/XMLSchema-datatypes#unsignedInt

That would be weird, and I don't think you mean to say this. If you do
please provide a rationale that fits with how we expect things like URI
references and QNames to fit into other W3C recomendations such as XML
Namespaces, XLink/XPointer, RDF etc. The more I read these and similar
details, the more confused I get about the overall vision of the Web as
embodied by the suite of W3C Recommendations.
