point taken - didn't think of that
However there is still a problem - I don' think the IdentityHashMap works
correctly.

The following doesn't produce the correct result
count(PLAY/ACT/SCENE[1] ) returns 1
when I take out the identity map I get 5 but then all the ancestor test
fail! (obvious to me now )
So, I'll commit my version of the DefaultLocationPath as I'm pretty sure it
is correct - can you look at the IdentityMap issue - all the ancestor test
are currently broken
