Secdir review of Registration of Second-Level URI Namespaces Under "ietf" draft-leiba-urnbis-ietf-namespace-01 Do not be alarmed. 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. From the Abstract: RFC 2648 defines the "ietf" URN namespace, and defines a number of sub-namespaces. RFC 3553 defines an additional sub-namespace, "params", and creates a registry to document allocations under that. But there is no registry that lists, in one place, all sub-namespaces of "ietf". This document creates and populates such a registry. I agree with the author's assessment that there are no security ramifications. Hilarie
