I don't think there is a ticket for this, but it would be nice if
there were standard ways to put a few more items into the DMARC part
of an A-R header, in particular the p= and pct= values and the
location of the policy record if it's not the same as header.from.

None of the existing ptypes really apply here (in particular "policy" is
for local policy, not a policy you found somewhere else.)  Perhaps call
it polrec for policy record and add polrec.p polrec.pct and polrec.domain.

I have never understood all of the indirection involved in defining
stuff for A-R but I'm hoping Murray can help out.

R's,
John
