No and no. I'm as surprised by this as you are. Is it really true that 
one can't separate out the Jaxen Jars and ignore the query method? I'll 
have to test that. I deliberately do not expose any of Jaxen in the XOM 
public API. I also want to avoid requiring the ICU jar for people to 
don't use it. That's also quite large (though ditching that dependency 
and writing my own NFC code is on the TODO list, simply because I don't 
want to carry around that extra jar)

When does Java calculate a unique ID of its public API? Is this some 
serialization thing?
