It seems like the Working Draft is describing a 'global attribute' which
should have an explicit namespace property (like XLink attributes) to
interoperate among different vocabularies.  Instead, the draft leaves
vocabularies on their own recognizance for this one.

This is something that will take some sorting out.  I don't think xml-dev
even figured out that global attributes were a separate and somewhat weird
category until a few months after the spec had come out, and XLink was
really the first spec to make heavy use of them.

Afraid so!  There's also a discussion on xml-dev about this right now:
