Objective BRSKI_JP not formally defined and name is confusing

[EskoDijk]

Problem with BRSKI_JP: it's used in an example as GRASP objective, but not formally introduced.

Also the name is a problem: it sounds like a Join Proxy advertising itself as a Join Proxy to Pledges. But that's not the case: the document says it's used by a Registrar to advertise its CoAPS (CoAP-over-DTLS) service. So to stay consistent with earlier and other work we should use e.g.

BRSKI_REG (given that BRSKI_REGISTRAR would be quite long)

Also this fits with the name

BRSKI_RJP

which can be interpreted as "BRSKI Registrar Join Proxy protocol". This is the special access protocol that uses a CBOR element.

[EskoDijk]

Update: the BRSKI_JP is actually defined in constrained-voucher. (Should it be moved?)

Maybe discuss here why the objective name is "BRSKI_JP" since the objective is for the registrar to announce itself?
Or should we read objective the other way around i.e. "objective is for the Join Proxy to connect to me"? (confusing)

I think that the JP part referred to the protocol we are advertising, but it does seem wrong now.

Labeled 'future' to be dealt with in discovery draft, if required (although note that applicability for cBRSKI in ANI is still a question whether it's relevant)
