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.

>Knowing the right order appears to be a little bit confusing sometimes.

That's for sure.
