Note that lxml (which implements an ElementTree compatible API on top of 
libxml2) was using the 'etree' as a *module* (not a package name) before 
this move of ElementTree in the core. I had some discussions with 
Fredrik about making ElementTree in the Python core consistent with 
lxml, but no luck there.

I.e., this in ElementTree:

from elementtree.ElementTree import Element

is this in lxml:

from lxml.etree import Element

and I believe in python 2.5 it's now:

from xml.etree.ElementTree import Element

which is not good in my opinion... (though also not a disaster)
