How does Python3 support xPath, xQuery and XSLT respectively?

I'd like to have some most updated info on python 3 support of XML， since most info I've googled is prior 2008.

Specifically, 1) how does Python 3 intersect with xPath? Is it exclusively through etree module? 2) does Python 3 natively support the concept of xQuery? I don't find any module yet, is there any? 3) with some strong pythonic modules like Mako, is XSLT still relevant in python? I personally found Mako is more powerful than any template handling tools.

Please give some overview info here. Thanks.
