Hm. About this, see XPath 2.4. ancestor is a reverse axis. I don't see
anything here that changes the order to document order.

Oops! You're right about this. XPath 4.2. Somehow I had it in my head that
it was the first in the set. (Maybe an earlier version of the spec had it
that way?) Thanks for helping me upgrade my brain.
