XOM API for Processing XML with Java

I think the URICache in Verifier was very good the way you had it.

The lastet CVS improvement also checks for equals(). I think that's a 
step back when you look at it from the point of lock contention in 
multi-threaded environments. You need to keep any work inside static 
synchronized blocks as brief as possible to avoid lock contention 
becoming an issue. So I'd happily trade 10% performance improvement for 
strongly reduced lock contention, leading to much better scalability. 
The URIs are almost always constants anyway...
