Serhiy, note that _SimpleElementPath is now gone in 3.3, since ElementPath.py is always there in stdlib. Could you update the patch to reflect this?

Another thing. I'm trying really hard to phase out the doctest tests of etree, replacing them with unittest-based tests as much as possible. The doctests are causing all kinds of trouble with parametrized testing for both the Python and the C implementations. Please don't add new doctests. If you add tests, add them to existing TestCase classes, or create new ones.
