I thnk its based on the StackIterator, which calls for the parent
iterator, and then that object's parent, and then that object's
parent, and so forth.
Ancestor ends up being just a synthesis of the Parent axis recursively
applied. It's one of those axes that you get 'for free' when you
provide a parent axis iterator.
