Sorting elements by their position within their parent node will not
guarantee document order in any case, so you will have to switch tactics
even further.
Imagine this:
<A>
<X>
<C>foo</C>
</X>
<X>
<B>bar</B>
</X>
</A>
and this path: "//B | //C"
Both the B and C element have position 1 with respect to their parent..
so you have to traverse the whole tree to establish document order
post-hoc. It's much cheaper to hack it into Jaxen, but I would protest
if it was turned on by default, because it ruins performance.
What I found worrying however, is that Jaxen doesn't throw an exception
with the path you tried :)
