That makes a lot more sense. It occurs to me now that I could probably 
speed this up for the common case by caching three or four namespace 
URIs (it's a rare program that uses more than that) and not reverifying 
them for each and every element. Then however expensive the URI 
verification code is, you'd only need to pay the price once, at least 
most of the time. That might remove the need for one of your patches.

I'll look at your benchmark code and see what I can do. Does the code 
include the sample documents as well? One thing I've noticed while 
looking at this is that a lot of my tests cases I've been using to 
optimize are namespace free. I do need to do some more testing with 
documents that use namespaces.
