Re: [dnssd] Draft: A DNS Query including A Main Question with Accompanying Questions

I think that this design can cover more use cases.

For example:

Case 1) Muti-types for the same name:
  – Query example.com for A and AAAA
When asking about a QTYPE=A RRset, a QTYPE=AAAA RRset may also
be of use [RFC 5321];

Case 2)Muti-types for the same name and its sub-name:
– Query www.example.com for A and AAAA, and _443._tcp.www.example.com for TLSA
When asking for some RRset of www.example.com about A and AAAA, records of a sub-domain name such as _443._tcp.www.example.com
for TLSA may be of interest[RFC 6698].
