Let's say that this now officially starts working-group last call on

In the Abstract:
"This memo registers an extension report type to ARF to be used for
reporting forensic information about messages that fail one or more
message authentication schemes in use by the purported sender of the
message."
The term purported sender sounds like one borrowed from SPF. DKIM
does not use such a term. I suggest reusing some wording from ARF
such as "to report feedback about received email" or use the text
from the Introduction section.
In Section 3:
"The current report format defined in [ARF] lacks some specific
features required to do effective sender authentication reporting."
I don't think that "sender authentication reporting" is the
appropriate term. Please let me know if the comment is unclear and I
will expand on it.
"Authentication-Results: This field MUST be formatted as defined in
[AUTH-RESULTS], except that it MUST include explicit results for
both DKIM and SPF."
John Levine already commented on this.
"Reported-Domain: As specified in [ARF]. This field MUST appear
exactly once."
This is an optional field in ARF which can appear more than once.
"If this information is either not available at the time the
report is generated, or the generating ADMD's policy requires it
be redacted, a value of 0.0.0.0 MUST be used."
Why must 0.0.0.0 be used?
In Section 3.2.1:
"policy: The message was not delivered to the intended inbox due
to authentication failure. The specific action taken is not
specified."
The term "policy" is confusing. is this a "discard"?
In Section 3.3:
"The DKIM-ADSP-DNS field MUST be included in the report."
What is the DKIM-ADSP-DNS field?
Section 7.4 discusses about Envelope Sender Selection. I suggest
reusing the idea from Section 5 of RFC 5965 as it is easier to build upon ARF.
The DKIM reference should be updated to RFC 6376. MAIL should be
updated to RFC 5322.
In Appendix B:
