Your entire premise seems to be based on an article of faith that 
collections cannot change. While this position is logically 
self-consistent, I find nothing inconsistent in the alternate position 
that collections can change. Furthermore, I think allowing mutable 
collections of names is more practically useful for the development of 
the Web and other XML-based technologies.

In your example, I see no fundamental reason why we should consider the 
namespace URI to refer to the stuff in the bag rather than the bag 
itself, or vice versa. Pick whichever interpretation is most useful. 
more than half a decade's experience had pretty well come down on the 
side that it is very problematic to use namespace URIs as a version 
control mechanism, so we don't do that.
