There is a further problem, validation (the issue Tonico raised is one of
well-formedness.) Will the validators accept a namespace such
as 'attr' when they can't tell what is allowed to be in it? ZPT is
supposed to be a roundtrip XML solution, so validation should be an
important concern (just as much as well-formedness).
