What I did for this was to add something to 6.1 reading "Verifiers MAY
ignore the DKIM-Signature header field if it contains an "x=" tag and
the signature has expired." I then added to the end of 6.1 "If there
are no valid signatures remaining after this step, a verifier MUST NOT
proceed to the next step."
If we are to keep the x= parameter, this change to the text strikes me
as an extremely constructive navigation of the challenges to its use.
and lest my wording be confusing: +1.
