Let's back off a bit. XML is a language for *creating* markup
languages. No more than that. Some of those languages may do something
of what you said. Many or most will not. XML per se has no data model
beyond e.g. elements, attributes, and the like. Adding XPATH adds no
semantics besides associating certain URIs with certain elements.
Actually, *RDF* can be thought of as creating an implicit space of the
type you speak of. And although there is a standard XML representation
for RDF, there are many other non-XML ones too.
