I am a bit confused about the agreements part between registries and 
registrars but I don't think it is a blocking factor for our discussion. 
At the end of the day, the Domain owner provides contact information to 
a Registrar and these records are kept by the Registrar. Registrars 
probably don't need to validate anything (e-mail addresses, phone 
numbers). Domain owners have the incentive to provide accurate 
information so that they can be contacted if something bad happens with 
their Domain. If this information is inaccurate, the CA will probably 
not be able to reach the Domain owner to validate. There have been cases 
of Domain hijacking but I don't think that the CA/Browser Forum should 
try to solve this problem.

We already have a definition for Domain Name Registrar which covers the 
ccTLD cases.

"Domain Name Registrar: A person or entity that registers Domain Names 
under the auspices of or by agreement with: (i) the Internet Corporation 
for Assigned Names and Numbers (ICANN), (ii) a national Domain Name 
authority/registry, or (iii) a Network Information Center (including 
their affiliates, contractors, delegates, successors, or assigns)".

We don't currently define "Registry" but there are several places where 
we use "registry-controlled, or public-suffix". Perhaps we can leave it 
as is.

How about using simpler language?

"Domain Contact: The Domain Name Registrant, technical contact, or 
administrative contract (or the equivalent under a ccTLD) as listed in 
the WHOIS record of the Base Domain Name or in a DNS SOA record or 
through direct contact with the Domain Name Registrar."
