Currently while those are being defined in CoRE drafts we can avoid collisions, but when other WGs or SDOs start defining them...

Recently several CoRE drafts have been written that do specify well-known values for those fields, so it starts to become obvious that those registries would be useful. If I understand right, your recommendation would be that we define those registries in the IANA section of this document? I would be in favor of doing that.

Where are we on resolving topic? This is closely linked with the registry proposed in senml.
