Hi,

I would like to discuss the issue of developing YANG modules that mirror IANA 
registries. The main objection, raised in DNSOP WG in relation to 
draft-lhotka-dnsop-iana-class-type-yang-02, was that the RFC containing the 
initial revision of the module doesn't get updated along with the IANA registry 
(IANA is expected to keep the module in sync without updating the RFC). As a 
result implementors can use the obsolete snapshot from the RFC.

I am aware of three solution proposals:

1. use some kind of template instead of a YANG module

2. include only two or three entries of the registry as examples so
   that it is clear that it is not the complete list

3. keep the module in the document during the whole I-D stage but
   instruct the RFC Editor to remove it just before it becomes RFC.

I am personally in favour of #3. According to Randy Presuhn, who proposed it, 
this procedure was used during the preparation of BCP 47. It would require some 
extra coordination with with IANA but, apart from that, it should IMO work well 
and avoid the problem mentioned above.

Thanks, Lada
