Re: [IETF-PKIX] OCSP: Semantics of thisUpdate, nextUpdate, producedAt



Hi Marc,
    I don't agree with your first sentence. A CA might have a policy of
only updating its database periodically (for example because it keeps
the database itself offline and a read-only copy online). In that case,
even a responder that has direct access to the CAs database, might
still want to set nextUpdate.

In a spec like this, I would rather tell people what it means if they
do something rather than dictate policy to them.

Regards,
Ambarish
