I would suggest to raise this issue on www-tag. There is indeed a need
for clarification; I am regularly stunned by claims on such matters,
e.g. in http://tinyurl.com/6744o Dean Jackson claims that "W3C also
broke this rule when adding Ruby to the XHTML namespace ... W3C goofed
up and regret the mistake" and you seem to be in line with Dean here;
common practise is however to add new elements and attributes to "name-
spaces".

XForms 1.1 adds new features to XForms, W3C prohibes publication of
technical reports that add new features to a previous Recommendation
without changing the major version number. W3C also prohibes reusing
old version numbers if non-editorial changes are made. Refer to the
publication rules http://www.w3.org/2004/02/02-pubrules.html#head for
details. Refer to http://www.w3.org/1999/10/nsuri for namespace rules.
So it seems not all that relevant whether there is a rule against re-
using the XForms 1.0 namespace in XForms 1.1.

That would be most interesting, please make sure you include such a
discussion when raising this issue on www-tag.
