By no means.  One resource is the 2000-01-26 version of xhtml1, whereas
the other is the current version of it.  Each URI references a distinct
resource (though one may use RDF or DAML+OIL to declare that two
resources are "the same" in some sense).

Indeed.  Furthermore, if you GET your second URL sometime hence,
you may well get a different entity body (representation).  In
principle, at least, the relationship between resources (named
by URIs) and representations is many-many.
