IMHO, this is RFC 1034, section 4.3.2. It says "If a match would take
us out of the authoritative data, we have a referral. [...] Put
whatever addresses are available into the additional section, using
glue RRs if the addresses are not available from authoritative data or
the cache." In the example given ('dig @f.gtld-servers.net A
ns1.crsnic.net.') we are "out of the authoritative data".

I agree that RFC 1034, 3.7 says "Answer [section] Carries RRs which
directly answer the query." introduces ambiguity since, in the example
given, the A record directly answers a query.

Work for the IETF "DNS extensions" working group, which is currently
busy on a "profile" RFC? (See the attached message.)
