[Ietf-not43] Last-Verified Date Contact Element

[Rick Wesson]

Scott && IESG,

I realized that there is an item we have overlooked in the wg. In private
conversations, myself and others have noted that there is no way to
identify the last time a contact object was verified.

I propose that we add a "Last-Verified" date element to the contact object
so that registries/registrars may express the last time the object was
verified. Since contacts have no expiration date and the "last-modified"
date is irreverent to verification.

I believe that this will aid in identifying old, stale and irreverent data
within a registry and if the element is published in CRISP or whois to the
community in general.

I know it is late in the game for identifing issues with the epp proposals
so I have CCed the IESG.
