To me, this is a design issue more than a practical one: namespaces 
belong to markup while QNames belong to applications.

This is the same kind of question than:

- Why model communication protocols as layers?
- Why defined private classes?

It's allways more concise to access private classes, methods and 
properties directly and to short-circuit the layers of a protocol...

Allowing QNames creates a dependency between the applications and the 
markup which should not exist. It makes it more difficult to build 
applications relying on a "virtual XML" which is never serialized as XML.

These are things I find difficult to explain clearly, it's almost a 
matter of ethics ;=) something which just makes me feel very uneasy...
