I agree with this, but I'd go farther.  I think that even though RDFCore is 
not chartered to come up with a new data typing scheme, that they should 
consider defining XSD data types using URIs under the control of RDFCore, and 
providing a simple and normartive mapping between these and the XSD data types.

I think that given the current chaos of namespaces and architectures in the 
W3C, that this is the only safe approach for consistency *within* the RDF

I think this is similar to what I'm trying to say above.
