Protocol Quality
David Kessens reviewed this document for the IESG.
Note to the RFC Editor:
In section B.2, please add a new first paragraph:
ADD:
NOTE: omitting some critical additional data instead of setting the
TC bit violates a 'should' in Section 9 of RFC2181. However, as many
implementations still do that [TC-TEST], operators need to
understand its implications and we describe that behaviour as well.
In section B.2, in 2nd paragraph:
REPLACE:
Therefore, at least in many scenarios, it would be very useful if the
information returned would be consistent and complete -- or if that is
not feasible, return no misleading information but rather leave it to
the client to query again.
WITH:

information returned would be consistent and complete -- or if that is

In section B.3:
DELETE paragraph:
Additionally, to avoid the case where an application would not get an
address at all due to some of courtesy additional data being omitted,
the resolvers should be able to query the specific records of the
desired protocol, not just rely on getting all the required RRsets in
the additional section.
