The qualification on my claim was on the number of its promoters, not on its
necessity. It is not possible to guarantee an unambiguous attribute default -
or type, or anything about it, unless the attribute name is mapped to its
equivalent universal identifier. One may claim that the qualified name
suffices, but a) that is not complete, b) in some situations where it
succeeds, it already effectively enforces half of the specified namespace
mapping (true, the redundant half) as soon as it performs the name resolution
relative to the element identifier for names without prefixes.

It's not a matter of the situation.
