This is right at the beginning of Section 1 as motivation for clarifying the situation and to make it clear that this document is intended to apply to future redirection RRs (unless, of course, the document specifying them says otherwise). I could make this a bit more definite by saying "There has been a proposal for another redirection RR that would combine the effects of both CNAME and DNAME." In fact, there is a renewed effort to start work on such an RR just in the past few days. > Section 2 identifies two status bits as part of this clarification > document.

Well, the name of the document is "xNAME RCODE and Status Bits Clarification". I'm not sure why it would make that much difference to move Section 2 on status bits to a new subpart of Section 1. As you say, they are further discussed in Section 4. It seems to me that something can "clarify" with making any change. Given no objections in the DNSEXT WG to this material, I am inclined to leave it in. > Nits: > > In Section 3, the exclamation mark legitimately relays bewilderment here, > but unfortunately I think it should just be a period.

But I'm OK with changing it to a period. > In Section 4, the clause “if the following apply” should be amended by > adding “all of” or “one of” or something more specific. Sure, should be "all of".
