I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG.  Document editors and WG chairs should treat these comments just like any other last call comments.   This document (intended to become an informational RFC) reserves the URN Namespace Identifier “OIPF” for use by the Open IPTV Forum so that organization can assign globally unique URNs beginning with “urn:oipf:”. The security considerations section correctly states that there are no security considerations beyond those normally associated with the use and resolution of URNs in general.   This one does not require a lot of thought (at least with respect to security).                   --Charlie
