1. Introduction

   IODEF extensions via class extension through AdditionalData and
   RecordItem elements, per Section 5.2 of [RFC5070], generally register
   their namespaces and schemas with the IANA XML Namespace registry at and the IANA XML
   Schema registry at,
   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
   (, in
   Section 2.
