[bind10-dev] sorting RDATA in-memory

[JINMEI Tatuya / 神明達哉]

This is a question about the BIND 9 implementation, but I hope someone
in this list may have some clue.

BIND 9 sorts RRs of the same RRset in the DNSSEC order when it loads
the records into memory (unless the special compile time options is
specified).  Is there any reason for this behavior?  Obviously we need
to sort them when we need to compute the signature of the RRset, but I
don't see the need for it in answering queries.  I'm curious about
whether there's any other reason for the convenience of calculating
the signature.

Hopefully someone can clarify that...
