This reveals IMO a big mistake in thinking about configuration files.
The most important user of a config file is not the programmer who has
to get data out of it; the most important user is the user who has to
edit the config file. The outrageous verbosity of XML makes the above
example a complete usability liability.
Now, if you're talking about config files that represent options that
the user edits in a convenient application-specific options dialog,
that's a different story; I think XML is well-suited for that; but I'm
talking about the classic configuration file pattern where you use
your favorite flat-file text editor to edit the options file. In that
situation, using XML is insane.

I see no advantage in waiting until Py3K; this is not a language
issue and there is no problem with having several library modules (as
long as it's clear which one is deprecated).
