Hi Peter,

I generally agree with your list of statements, but #7 is imprecise:

To be more precise, the only entity that knows if a certificate for
their domain *did not undergo proper domain validation* is the entity
who was the domain registrant at the time of issuance[1].  Many other
types of misissuances can be detected by anyone, such as SHA-1,
encoding errors, illegal characters in dnsName SANs, overly-long
validity, etc.

Regards,
Andrew

[1] technically, at the time the CA is required to check, but that's
beside the point
