RFC 6685                   IODEF XML Registry                  July 20121.  Introduction   IODEF extensions via class extension through AdditionalData and   RecordItem elements, perSection 5.2 of [RFC5070], generally register   their namespaces and schemas with the IANA XML Namespace registry athttp://www.iana.org/assignments/xml-registry/ns.html and the IANA XML   Schema registry athttp://www.iana.org/assignments/xml-registry/schema.html,   respectively [RFC3688].   In addition to schema reviews required by IANA, these registry   requests should be accompanied by a review by IODEF experts to ensure   the specified AdditionalData and/or RecordItem contents are   compatible with IODEF and with other existing IODEF extensions.  This   document specifies that review.2.  Expert Review of IODEF-Related XML Registry Entries   Changes to the XML Schema registry for schema names beginning with   "urn:ietf:params:xml:schema:iodef" are subject to an additional IODEF   Expert Review [RFC5226] for IODEF correctness and appropriateness.   The IODEF expert(s) for these reviews will be designated by the IETF   Security Area Directors.3.  Security Considerations   This document has no security considerations.4.  IANA Considerations   This document specifies additional expert reviews for IODEF   extensions, on the XML Schema registry   (http://www.iana.org/assignments/xml-registry/schema.html), inSection 2.5.
