[cabfpub] Intermediate certificate names

That could be three different entities.
However, we realized during the discussion that the section actually mixes two issues: 1) information in the subject of the issuing cert and 2) information in the issuer field of an end-entity cert. To clarify, we're going to need to separate out the two issues.

I was speaking loosely. The actual definition from the BRs is that the CA is "An organization that is responsible for the creation, issuance, revocation, and management of Certificates."

So, in this case, the organization that is *responsible* is probably CA2. They oversee RA1, they have a contract with CA3. CA1 probably won't want to be responsible for CA2's operations. CA3 will say "we're just hosting, we have no liability for anything".
You can do this backwards, by saying that the organization named in the certificate is the CA and therefore is responsible; so, the real question is, as the CA issuing the intermediate, who do you trust to be responsible?
