I don't mind pointing people to ElementTree, despite that I disagree
whether the ET interface is "superior" to DOM. It's Stefan's reasoning
as to *why* people should be pointed to ET, and what words should be
used to do that. IOW, I detest bashing some part of the standard
library, just to urge users to use some other part of the standard library.

People are still using PyXML, despite it's not being maintained anymore.
Telling them to replace 4DOM with minidom is much more appropriate than
telling them to rewrite in ET.
