[cabfpub] New validation method

[Peter Bowen]

As ballot 190 is complete and fully effective, it seems like a reasonable time to start considering further validation method.  Amazon proposes the following new method.  As far as I know, this does not overlap with any of the existing methods.

3.2.2.4.12 Registrar challenge validation
Confirming the Applicant’s control over the request Domain Name by confirming the presence of a Random Value or Request Token in a response from the Domain Name Registrar or Registry received in response to a request containing an Authorization Domain Name.

Thanks,
Peter
