Right: what they _are_ is a way of uniquifying and globalising names,
and I think that they will do an acceptable job of that.  The problem
comes if people try to do anything else with them (such as specifying
inheritance, embedding documents in other documents, etc.).

Agreed: I would like to be able to include meta-data without being
forced to use the element type names that RDF chose.  XML-Link got
this one right.

All the best,
