DNS - multiple question with a single query

[Alan Clegg]

BIND does not support multiple questions in a single query.  :\
Based on draft-ietf-dnsext-edns1-03.txt

Multiple queries in a question section have not been supported in DNS
due the applicability of some DNS Message Header flags (such as AA) and
of the RCODE field only to a single QNAME, QTYPE, and QCLASS.

edns1 tried to change the tradition, but it then died (with other
proposed changes).
