This document extends PASSporT, a token for conveying cryptographically-signed information about personal communications, to include rich data that can be rendered to users, such as a human- readable display name comparable to the "Caller ID" function common on the telephone network. The element defined for this purpose is extensible to include related information about calls that helps people decide whether to pick up the phone.
