Re: [DNSOP] I-D Action: draft-salgado-dnsop-rrserial-01.txt

Dear group. Version -01 has substantive changes according to the
comments in the list.

The most important:

- qname is used to associate the serial's zone, and thus avoid
  associating it to the answer, that can be empty or multiple;
- its use is not prohibited in resolvers, but remains undefined;
- the length of the answer is defined as 0 for questions and 4 for
  answers;
- added SERVFAIL use in addition to NOERROR (optional);
- clarified use for NODATA;
- an applicability consideration is added that advises against its use
  in zones that do not make sense of the SOA's serial;
- a security consideration is added about the risk of not carrying
  dnssec signatures.

Regards,

Hugo
