QName interpretation is underspecified in the Datatypes REC, and this
will be corrected.  The issues list contains a proposed resolution [1]
to this problem which has been ratified by the WG, and I'm responsible
for drafting the erratum which will settle the matter.  Here's the
relevant section from the above reference:

  This should be clarified in the REC -- the intention is that
  unprefixed names are qualified iff there is a default namespace
  declaration in scope, i.e. as per element names, not attribute
  names, in XML 1.0 plus Namespaces.

  The definition should also make clear that the value space includes
  pairs of "no known namespace", local name, which correspond to
  unprefixed QNames when no default declaration is in scope.
