What I meant was something like this:

                type uint16;
                description
                    "The encryption algorithm is specified with a 16-bit
                    number extracted from IANA Registry. The acceptable

                    encryption algorithms for ESP and IKEv2.";

            }


Wouldn't this define what you need, without hardcoding all the valid
values from the snapshot of the IANA registry?

This would instruct the implementor to go to the IANA registry, notice
there what is obsoleted/deprecated, and they will know they will have
to check IANA when doing a release update.

Am I misunderstanding something?
