UPDATE: The problems with xpath="" are now fixed. The duplicate xmlns seemed to be an artefact of the test runner.

This test demonstrates the problem with xmlns="" and incidentally an issue with
the way test_nodes.py works vis-a-vis xsltproc / mod_transform / dv.diazoserver.

Note the double xmlns="http://www.w3.org/1999/xhtml" on the html node of the test_nodes.py version and no xmlns="" anywhere.
