* My idea
I prefer multiple query sections (with some restrictions)
and merged answers.
multiple query examples may be
NAME A + NAME AAAA + MX
NAME A + NAME AAAA + _443._tcp.NAME TLSA
NAME A + NAME AAAA + _sip._udp.NAME SRV + _sips._tcp.NAME SRV +
...
Many people may dislike QDCOUNT != 1.
EDNS0 option which contain additional query section may be
possible.
and there's my idea (draft-bellis-dnsext-multi-qtypes-02) which only
permits a single QNAME, but supports additional QTYPEs via an EDNS0
option.
Of these three solutions to the same problem, I prefer Ray's. It seems
less work to implement and less likely to trip up naively-implemented
DNS stacks.
