Re: [ietf-dkim] Updated proposal: get rid of x=

Add a new paragraph at the end of section 1.1:

A DKIM signature is intended to be verifiable for about the length of time of that it would take to transport the message in SMTP; this is almost always less than two weeks. The signature is not intended to be used for archival purposes, and verification of the signature after this period is not an intended or desired feature of the DKIM protocol.


This text doesn't seem to be able to make up its mind if it's informational
or  normative. It needs to be normative. Which is why x= is better since
we can recommend something squishy like around 2 weeks, but be able
change it in the future if needed.
