PROPOSED versus draft 28 section 4.7:
========
If a retrieved policy record does not contain a valid "p" tag, or
contains an "sp" or "np" tag that is not valid, then:
* The Mail Receiver MUST act as if a record containing "p=none" was
retrieved and continue processing;
If it were not for the appositive condition bringing about "sp" and "np", these
two clauses would have a sound meaning. Acting as if p=none after an invalid
sp= clashes. Let me try a different wording:
If, in a retrieved policy record, the policy to be applied, "p", "sp",
or "np", is specified with an invalid value, then:
* The Mail Receiver MUST act as if said policy had the value "none";
* The Mail Receiver MAY note the invalid "p", "sp", or "np" tag
in the optional "error" field of the informative section of the
DMARC aggregate report [I-D.ietf-dmarc-aggregate-reporting];
* If there is no "rua" tag, or if it does not contain at least one
syntactically valid reporting URI, the Mail Receiver effectively
applies no DMARC processing to this message.
I agree to mention the error field here. Yet, in such event, it is not
possible to report the value of the policy, so minOccurs should be 0.
The order of the last two bullets is beter reversed.
Best
