That's a separate issue. My question is if you're parsing ten different 
documents at a time, each of which uses the same three or four 
namespaces, if the namespace URIs aren't interned across parses, won't 
they tend to keep knocking each others namespaces out of the cache? Even 
though they're really the same URIs?
