It is not a *defined* mechanism.
The whole point of QNames is disambiguation, not interoperability.
"Do whatever you want" doesn't help interoperability on what has been  
defined at all and promotes things like:

In a User Interface if a model was clearly, it would make it possible  
	- User agent to display the definition of the property if requested  
(accessibility, usability)
	- Authoring tool to display a menu with choices of values and their  
definition when editing
	- Search engines to index content with help on definition when  
someone is using the search engine.

We could imagine that there is a way with XML, RDF, simple XHTML  
file, a way to create a reference which is explaining the goal and  
meaning of the new values and which is automaticly processable by  
user agents (including authoring tools and others).
