At the moment this is true, but Jim and I have discussed the possibility
of ZCatalog being treating the paths less atomically and more as a
sequence of nodes from root to the target, this way, you could ask the
catalog for all objects below a certain point that match search
criteria, etc.

And it looks like the event stuff is favoring paths also, I strongly
suggest we make sure any of these needs is captured in the proposed
traversal interface:
