Okay.

My immediate concern was that people would think that RDF created by
the RDF Core WG would be a good example.  As long as it's clear that
the Group knows this format is effectively broken, that's probably
enough.

Still, there should be a dc:description in the file and its schema
file giving a pointer to the postponed issue.  Since those documents
are expected to evolve even post-Rec, there's no huge hurry there.
Maybe the problem can be fixed post-Rec with a version-2 test setup.

Formally, this response is acceptable.
