Um... suppose the two URLs:

http://example.com/your-doctor --> "John Smith"

http://example.com/your-plumber --> "John Smith"

Does bytewise comparison of a resource really indicate that the two
resources are identical or even equivalent?

If we are really going to define namespace equality on the basis of
retrieved resource equivalence, we might need to invoke some sort of a RDF
framework (shudder) at the XML parser level (shudder,shudder) in order to
make this really work (even then, would it?)

I'd say that #1 is the only reasonable option.
