Ok, that clears things up a bit and explains the validation error.  I
also see how I can use etree.cleanup_namespaces before comparing the
xml output.

I guess the thing that I find strange is that there seems to be no way
to end up with the xml I started with in my example if I instead start
by instantiating an ElementTree object first.  Either you have the
validation error, fully prefixed namespaces, or one of the namespace
declarations removed (if you were to use cleanup_namespaces).

Thanks for your help!
