1.  Introduction

   This document relaxes the IANA rules for the Protocol for Carrying
   Authentication for Network Access (PANA) [RFC5191].  Rules for the
   following protocol fields, all defined in [RFC5191], are affected:

   o  Message Types

   o  Message Flags

   o  Attribute-Value Pair (AVP) Flags

   o  Result-Code AVP Values

   o  Termination-Cause AVP Values

   The rationale for this update is that there can be situations in
   which it makes sense to grant an allocation under special
   circumstances.  At the time of this writing, the IETF is in the
   process of approving one such allocation.  By changing the current
   IANA rules to allow for IESG Approval [RFC5226] as well, it has
   become 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 an allocation from a field of reserved bits, as long
   as a sufficient number of bits still remain for other purposes, and
   the PANA community is happy with such allocation.

2.  IANA Considerations

   IANA has updated the registries related to PANA Message Types,
   Message Flags, AVP Flags, Result-Code AVP Values, and Termination-
   Cause AVP Values, as specified below.  All other PANA IANA registries
   are to remain unchanged.

2.1.  Message Types

   The Message Types namespace is used to identify PANA messages.  Value
   0 is not used and is not assigned by IANA.  The range of values from
   1 - 65,519 are for permanent, standard Message Types, allocated by
   IETF Review or IESG Approval [RFC5226].  Previously, the rule for
   this range was allocation by IETF Review only.  [RFC5191] defined the
   range of values from 1 - 4.  The same Message Type is used for both
   the request and the answer messages, except for type 1.  The Request
   bit distinguishes requests from answers.

Arkko & Yegin                Standards Track                    [Page 2]
RFC 5872                     PANA IANA Rules                    May 2010

   The range of values from 65,520 - 65,535 (hexadecimal values 0xfff0 -
   0xffff) is reserved for experimental messages.  As these codes are
   only for experimental and testing purposes, no guarantee is made for
   interoperability between the communicating PANA Client (PaC) and PANA
   Authentication Agent (PAA) using experimental commands, as outlined
   in [RFC3692].

2.2.  Message Flags

   There are 16 bits in the Flags field of the PANA message header.
   Section 6.2 of [RFC5191] assigned bit 0 ('R'), 1 ('S'), 2 ('C'), 3
   ('A'), 4 ('P'), and 5 ('I').  Allocations from the remaining free
