Title: skipping a subtree in xpath evaluation

Hi

Is there a way to skip a portion of the dom tree during an xpath traversal?
[I can also change the xalan source code and submit a patch for this functionality.]

The dom tree that i am traversing is pretty big but one subtree is very expensive to traverse due to its size. The xpath queries don't normally require me to  traverse that subtree so i want to skip it for normal xpath traversals.

The problem comes with // expressions or following:: or preceding:: expressions. the xpath engine  starts traversing the whole dom tree and the efficiency is significantly reduced.

Can i put some restriction in the xpath engine for this?
