I've just replied in the upstream bug:

  This would not be a satisfactory solution as the goal is to be
  readable by HTML parsers *and* XML parsers. The solution of using
  xmlns="http://www.w3.org/1999/xhtml" and avoiding prefixes for
  HTML elements works. Perhaps that's the correct way of doing, but
  I'm not sure.

Now, I'm not even sure that this is a bug. The XSLT spec doesn't seem
to specify the behavior when an "excluded namespace" is used in the
result tree like in my example.
