It shouldn't, but that doesn't mean it won't.

You can't ask questions about performance without saying what processor you
are concerned with.

And the best answer to performance questions is always: measure it.

Incidentally, it's not true (from XSLT 2.0) that the inputs have to be
asymmetric. I will often supply both inputs as stylesheet parameters, and have
no principal input document.
