[cabfpub] Help to support SHA-1 for POS terminals

I agree there needs to be a vendor-neutral process. I just finally hit send on a reply to Dean’s email from a month ago that proposes an option.
A different option that might work for many terminals would be to create a new CA with a cross-cert with an EKU extension that contains a custom key purpose. I suspect that many terminals do not implement EKU constraining of CAs while browsers so, so that might be a more generic solution.

If there is, or if there is going to be, a process for allowing CAs to issue SHA-1 SSL certificates on a case by case basis from roots that are currently in the Root programs, then we would like to do that.
