Bruce read the antitrust statement.


Meeting minutes from Sept 9th were approved.


Ballot status:

CSC-9 and CSC-10 both completed IPR and were published.



Ian said to wait to discuss in favor of discussing CSC-11.



Ian shared current redline on the list for the discussion period. Voting
will start on the 24th.


Invalidity Date ballot:

There has been good discussion on the list. Ian confirmed that the current
and previous versions of Windows ignore the Invalidity Date and instead use
revocation date. One of the main open questions is how to handle the
Invalidity Date extension and its value since it serves no purpose in the
CRL. Rob suggested that we prohibit the extension from appearing, since it
increases CRL size.


It was agreed that it is strange for the invalidity date value to be
different from the revocation date value given Windows's processing, so the
requirement in the proposed ballot for them to be equal starting from the
effective date will remain. Bruce and Ian indicated that the current
proposal of February is too aggressive. The group agreed for a summer 2022
effective date.


On the point raised on the list for adding a "Application of RFC 5280"
section, there was a concern that adding that section and defining the
revocationDate semantics there would define the CRL profile specification in
multiple separate locations, which may be confusing. The group agreed to add
some language calling out the practice of backdating the revocationDate as
violating the SHOULD NOT of RFC 5280 in the current CRL profile section and
will potentially move this content to an "Application of RFC 5280" section
as part of the 3647 reformat.


F2F Agenda:

- Have a brief WG status overview

- Reserve most of the time for signing service. Ian said there are a lot of
inconsistencies and oddities in the CSBRs surrounding Signing Services that
need to be addressed.


The meeting likely will be held on October 7th but may be cancelled if there
are no agenda items.


There was no other business; meeting was adjourned.
