Isn't it a bit confusing to say that it returns it in reverse document
order? My understanding is that ancestor:: is ordered most immediate
first i.e direct parent, then parent of parent and so on, all the way up
to the root. This happens to be equivalent to reverse document order due
to the way xml trees are serialised, but that is not how I would think
of it when using them.

Is the preciding sibling axis ordered by document order?
