Take care with quantifiers, please.

Some uses of XML+Namespaces are consistent with web architecture,
e.g. the way RDF maps qnames to URIs, and some are not, like
the example above.

XML+Namespaces overlaps with Web Architecture; some uses
contribute to the Web of resources, some don't.

The ones that don't aren't necessarily evil; they
just don't participate in the network effects.

No, just an issue to be aware of.
