This seems like the best solution, but I'm not sure if it has any effects on the query optimizer, which relies on the type information. I just think there must have been a reason why Type.NODE is returned and not Type.EMPTY. I suggest I change the code locally for a while and see if it triggers something we can't overlook right now.
