Invalid or repeated p= tags are a problem, but possibly they don't
completely disqualify a record.
The concept of 'partial' disqualification points to the problem of
trying to be subtle in specifications.
A specification should provide and demand simple details and simple
handling of problems.
If a domain owner cannot produce a DMARC record that is correct, then it
is far too likely they don't know enough to participate in DMARC.
Here, the simple rule should be:
An invalid DMARC record MUST be treated as if no DMARC record is
present.
