[Servercert-wg] [DIscussion Period Begins] SC-070: Clarify the use of DTPs for domain control validation

[Aaron Gable]

Hi Eva,

I think the requirement is clear: the contact information must be obtained
directly by the CA. If a validation specialist is using a browser to access
WHOIS information that has already been gathered by the CA, then as long as
that information was "obtained directly by the CA", the requirement has
been satisfied. The requirement is on how the CA acquires the information,
now on how individuals within the CA's staff act on that information.
