Section 3.2. says:
3.2. Variable-Length Parameter Format M3UA-Specific parameters. These TLV parameters are specific to the M3UA protocol: Registration Result 0x0208 Deregistration Result 0x0209 Local Routing Key Identifier 0x020a
It should say:
3.2. Variable-Length Parameter Format Common Parameters. These TLV parameters are common across the different adaptation layers: Registration Result 0x0014, Deregistration Result 0x0015, Local Routing Key Identifier 0x0018,
Notes:
As the above three parameters mentioned are used for the same purpose in RFC 3868 and in RFC 4666. So the above parameters in RFC 4666 Section 3.2, the M3UA-Specific parameters can be considered to move them into the common parameters section 3.2 of RFC 4666 with the above sepecified values.
The advantage could be, for one who implements both SUA & M3UA can use the same encoding and decoding mechanisms/code for both the implementations.
--VERIFIER NOTES--
Per discussion on the SIGTRAN list, this is a fundamental and non-interoperable change to the protocol.
