Message 100846 - Python tracker

The "no header" thing is very much done on purpose, and it's documented in the upstream ElementTree documentation.

I suggest dropping this "Python 3 exists in its own universe" nonsense; it's not very professional, and it's hurting Python, its users, and all third party developers.  The "things I don't understand are braindead" stuff is less of a problem; that only hurts yourself.
