I have reviewed this document as part of the Operational directorate's ongoing
effort to review all IETF documents being processed by the IESG.  These
comments were written with the intent of improving the operational aspects of
the IETF drafts. Comments that are not addressed in last call may be included
in AD reviews during the IESG review.  Document editors and WG chairs should
treat these comments just like any other last call comments.

Summary:
   This document defines extensions to the vCard data format. It adds Contact URI property and two-
   letter Country code parameter to vCard data. 
   This is used to implement the operational profile for Registration Data Access Protocol (RDAP)  according to Temporary Specification for gTLD Registration Data published by ICANN.
I do not see any operational or manageability related issues due to this addition.
