IMHO, unless the SSP draft is changed to comply with RFC 4871, the WG should consider adopting the ASP draft instead.

First, I don't agree that SSP did not comply with RFC 4871.

No. RFC 4871 does not comply with SSP.

How so?

From my standpoint, ASP/SSP-02 both provided unprotected considerations in DKIM-BASE.

ASP::DISCARDABLE completely changes the semantics of DKIM-BASE failures state change to "no signature" to one where a failed signature exist.

Likewise ASP::ALL offers no protection against fraudulent 3rd party signers. This is not what I call adding a SECURITY WRAPPER around the DKIM-BASE signing expectations whether forged 1st or 3rd party.
