I'm not going to do it any time soon, just running it by you to see 
whether I comprehend it now or whether there was an approach I missed. 
It looks rather hopeless to periodically clean up dictionaries in the 
library I'm building, so I'll just hope it won't become a big issue. I 
don't expect it to start taking up a lot of space except in your 
aforementioned ID case. There aren't that many different tagnames and 
namespace URIs in the world, after all.

Right, I said it longer but that's my conclusion.

It's definitely an interesting thing to consider for a fast Python 
string lookup hash table.
Thanks for the info!
