It seems to me that several people who are arguing to kill = ae essentially
aguing that it has the same semantics that I beleive are the strongest that
can be attached to x= and conclude that these semantics are not suficient to
justify inclusion. Others argue that the semantics are ambiguous and it
should go which is not so far from saying the semantics are clear, just
different to the ones presented.
I suggest then that we take a quaker poll type approach and put in the full
range of options rather than require people to commit now to a yes/no vote.
The range of options I see is:
1) Keep x=, signers should be able to limit the time period in which the
accept resonsibility
2) Keep x=, signers should be able to state in the signature that they won't
support the key retrieval indefinitely.
3) Delete x=, the semantics are ambiguous, people think of it as message
revocation, they should not
4) Delete x=, signers can state the key support interval in SSP
5) Delete x=, time in seconds since 1970s invites 32 bit Y2K type issues
6) Other reasons
My prefered options are 2 and 4 equally. I reject 1. I can live with 3 or 5.
