Well. Then it means that between attributes {}"foo" and {xhtml}"foo" applying
to element {xhtml}bar, the one {xhtml} user agents should deal with is the one
with no namespace. Please allow me to find a little bit incoherent, to say the
least...

Can you please explain me why attributes applying to XHTML elements have
to have no namespace ? Giving them a namespace is not a blocker for other
vocabularies since it's possible to build an RNG schema defining only
attributes.
