I think this follows directly from the natures of resources as defined in
RFC 2396 and the distinction between a resource which is named by a URI, and
the network entity which results from the resolution of a particular URI at
a particular point in time. A type is a resource not its associated network
entity.

Henry is stating that the normative prose in the XML Schema spec makes such
assertions about the datatypes (my paraphrasing).

I'm having trouble parsing this. Please explain.
