Status of This Memo
This is an Internet Standards Track document.
This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 5741.

This document relaxes the IANA rules for Multimedia Internet KEYing (MIKEY) [RFC3830]. The IANA rules defined in [RFC3830], [RFC4563], [RFC4909], and [RFC5410] are affected. In addition, the rules specified in [RFC6043] are re-specified here.
Most of the values in MIKEY namespaces are divided into two ranges: "IETF Review" (or "IETF Consensus" as it was previously called) and "Reserved for Private Use" [RFC5226]. This document changes, for majority of the namespaces, the requirement of "IETF Review" to "IETF Review or IESG Approval" [RFC5226]. For some namespaces, the requirement is changed to "Specification Required" [RFC5226].
The rationale for this update is that there can be situations where it makes sense to grant an allocation under special circumstances or that time has shown that the current requirement is unnecessarily strict for some of the namespaces. By changing the current IANA rules to also allow for "IESG Approval" [RFC5226], it becomes possible for the Internet Engineering Steering Group (IESG) to consider an allocation request, even if it does not fulfill the default rule. For instance, an experimental protocol extension could perhaps deserve a new payload type as long as a sufficient number of types still remains, and the MIKEY community is happy with such an allocation. Moreover, for some registries, a stable specification would be a sufficient requirement, and this is thus reflected in the updated IANA rules. For instance, an RFC via the Independent Stream at the RFC Editor is sufficient for some registries and does not force an IETF evaluation of a particular new extension for which there is no general demand. Nevertheless, "IETF Review" is still encouraged (instead of using the "IESG Approval" path) if there is doubt about whether or not it is needed for a new allocation.
This specification does not change the security properties of MIKEY. However, when new values are introduced without IETF consensus, care needs to be taken to assure that possible security concerns regarding the new values are still addressed.
Section 2 relaxes the requirements from those defined in [RFC3830]. A number of namespaces now have the "IETF Review or IESG Approval" requirement, when they previously had the "IETF Review" requirement. In addition, some namespaces now have the "Specification Required" requirement.
Section 2 relaxes the requirements from those defined in [RFC4909]. The OMA BCAST Data Subtype namespace now has the "Specification Required" requirement. Note that [RFC5410] obsoleted [RFC4909] but does not actually define the IANA rules itself. As a result, from now on, this RFC defines the IANA requirements for the OMA BCAST Data Subtype namespace.
There are no changes to the rules specified in [RFC6043]. However, for sake of completeness, Section 2 re-specifies these rules in this document, and from now on, this RFC defines the IANA requirements for those namespaces.
