Ted and Larry,

If the question is really about UTS #46, I'd encourage everyone
relevant to read RFC 5704, substituting IDNA and various Unicode
actions for MPLS and ITU-T as needed.   The point is roughly the
same: the Unicode Consortium decided that a (somewhat
incompatible) "improvement" to IDNA was needed, could not get
consensus for that specification in the IETF, and so went off
and wrote their own.
