Actually, the last sentence above is not duplicated in the draft.

This draft brings together the aspects of the AA, AD, and RCODE bits
related to xNAME RR query cycles and expresses them clearly and
succinctly. As such it has been approved by the DNSEXT WG. I do not
believe that text has to make a change to be a clarification.

Yes, thanks for pointing this out. "BE" should probably be lowercase.

That was the mailing list at the time of the -00 personal draft
version. Sorry I missed updating the mailing list reference somewhere
along the way.

Thanks,
