This text basically says that if the criteria in §5 is not met, then
the specific entry must not be in the RFC.  At some point in the
future (when the §5 criteria is met), publication of the entry can
proceed -- presumably in a different RFC.

As Alissa mentioned in her DISCUSS, the text needs to be generalized
to cover specifications from other SDOs.  I'm not sure how preventing
publication would work there.

The criteria in §5 talks about "industry interest, or has seen
deployment", which makes me think about how early allocation would
work.  If interest/deployment is part of the criteria to be in the
registry, then early allocation "to facilitate desired or required
implementation and deployment experience" [rfc7120] would seem to not
meet the requirement.  Wouldn't it?

Do you (authors/WG) see value in documenting private/experimental
metrics?  I imagine that one way to prove interest/deployment is to
experiment (vs early allocation).  These would not pass the §5 hurdle,
but may need to be documented somehow.  In the IETF the WG could limit
publication to a draft (for example), but in other SDOs an actual
specification could end up being published...

Sorry to add more questions; I just want to make sure all the bases are covered.

Thanks!

Alvaro.
