I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG . These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments.   This document defines the URN namespace identifier for the entertainment industry's registered identifiers for audiovisual works. As such, it only specifies the syntax of these identifiers and the Sec Cons sections looks adequate to me. Thanks, -- Magnus
