A specification providing a choice of labels/settings needs to have a 
shared understanding of what those labels mean.

It seems pretty clear that DMARC's p= hasn't had that, to date. There is 
no consistency to the criteria used to set the label and, I suspect, 
little consistency to how a receiver's filtering engine uses it.

We need to settle on text that resonates with a consistent 
interpretation, by both domain owners and email receivers.

I've offered an approach that might permit reaching that community -- 
not just IETF -- rough consensus.

At this point we need to get suggested revisions for improvement. For 
now, I don't have better text to suggest.
