Use of BCP14 language for requirements

[SpencerDawkins]

@fluffy mentioned the use of BCP14 terms for requirements in this draft. That's allowed, but not required (:upside_down_face:), and is left to each working group. I'm entering the issue here, so we don't forget to talk about it.

When we know what the working group expects, we can do what's necessary to reflect working group consensus.

From @fluffy,

I don’t care much about this and fine if you do but just to explain … the definitions are not really very clearly defined in the requirements context. They ware written about the way a protocol would interoperate. Then we end up in arguments about if something is SHOULD or MUST and should gets uses as “nice to have” which is not what it is defined as. Finally we get into the question of if the requirements say MUST be able to do X, but the WG protocol does not do X, what does that mean for doing the pub request of the protocol draft.

Throughout the doc there is a mix of "should" and "SHOULD", which is a bit confusing.

I agree that we need to figure this out ...

I added the "Priority for discussion" tag before IETF 117, but since we didn't present this draft at IETF 117, I still don't know what the working group thinks. 🙃

Given that this issue has been stalled for a while, I agree with @fiestajetsam, that we do a brief review of existing language, and write a PR where required.

At a minimum, I need to be looking for uses of lower-case BCP 14 terminology, to make sure they are intentional.

From @SpencerDawkins and @fiestajetsam -

• James still thinks normative language is helpful in this draft
• Spencer doesn't strongly think that it's not
• James will scan the existing BCP14 language in the draft for consistency, and propose a PR accordingly.

@SpencerDawkins and @fiestajetsam agree that we don't need (and don't want) normative text in this document. James will execute the existing BCP14 text and remove the reference to BCP14.
