In article <CABuGu1rSyifv0B9RtD3_R2ex-sh+nVrh4Q3H=kU=ZsDWzVRAgQ@mail.gmail.com> you write:

I think what it means is that if there's a DMARC record on a
subdomain, it won't see any np= in the org domain or the PSD.  I agree
the wording could be better.  I also don't understand what possible
meaning an np= on a subdomain record would have.
