... DNAME was kind of the "third record in." The change in it's "status" pertained to the role it played in supporting bit sting labels - which is why the "reverse tree" is mentioned in the deprecation. Looking at the document now, the document ought to have read "the use of DNAME RRs in the support of bit string labels is deprecated" - based on my memory.
I wasn't there, but that's what the meeting notes seem to say, and that's what the people who were there all seem to agree on. Not that it matters; the type is defined and at least one authority server implementation will synthesize protocol-compliant CNAME RRs in the presence of DNAMEs, and so the approach documented at www.isc.org/pubs/tn/ will universally work OK. -- Paul Vixie
