Information Field and Protocol Identifier in the Q.2941
Generic Identifier and Q.2957 User-to-user Signaling for
the Internet Protocol per [RFC3033].
------------------------------------------------------------------

When the Identifier related standard/application field in the
Q.2941.2 Generic Identifier information element is the IPv4, ST2+,
IPv6, or MPLS, numbers between 0x10-0xFD in the Identifier type
field are reserved for IANA assignment.  These numbers are allocated
through an IETF Consensus action.

When the Protocol discriminator field in the Q.2957 User-user
information element is the Internet protocol/application, numbers
between 0x03-0xFD in the Internet protocol/application identifier
field are reserved for IANA assignment.  These numbers are allocated
through an IETF Consensus action.

Note that assignment of the Identifier related standard/application
field in the Q.2941.2 for the Internet protocol is as follows:

     0x03: IPv4.
	
     0x04: ST2+.

     0x05: IPv6.

     0x06: MPLS.

In the above case, assignment of the Identifier type field in the
Q.2941.2 is as follows:
  
     0x01: Session.

     0x02: Resource.

     0x10-0xFD: Reserved for IANA assignment.

     0xFE: Experiment/Organization specific.
