I'm not clear what route you are advaocating:

 1. Are we going to fork and fix Expat? I've been waiting quite a while
for a response from James on this issue.

 Ease of implementation: 6/10
 Ease of maintanance: 3/10
 Technical correctness: 10/10

 2. Are we going to implement new namespace handling ourselves in C
code? (ignoring Expat's namespace features?)

 Ease of implementation: 3/10
 Ease of maintanance: 6/10
 Technical correctness: 10/10

 3. Are we going to try to reverse-map from URIs to prefixes? And what
about when there are two possible prefixes for the same namespace?

 Ease of implementation: 8/10
 Ease of maintanance: 10/10
 Technical correctness: 2/10

Implementing something in Python is a stop-gap until we choose the
least-bad of these approaches.

I would multiply ease of maintenance by 10 and ease tecnical correctness
by 100 because they are so much more important than initial difficulty.

So "2" would probably be the best unless we hear from James Clark. Who
wants to implement it, though?
