Hello Orie,

(adding JOSE cc)

I am supportive of defining AKP semantics for seed vs private key forms,
but I would like to know whether to align fully with LAMPS in terms of
expanded, seed, or both is necessary. It is entirely possible that's a
discussion that happened and I am not aware of it, in which case I
apologize. I can imagine a JWK representation restricted to just the
following combinations would work just fine as well and would lead to less
edge cases to be handled by users and libraries

   - kty, alg, and seed (pub missing, priv missing; not required given a
   seed is present, no consistency checks required)
   - kty, alg, and pub
   - kty, alg, priv and pub (seed missing)

Interested in what you think? Are we just patching an almost done piece of
work at this moment? Or is there a moment to step back and come up with a
clean setup given the LAMPS outcome.

S pozdravem,
*Filip Skokan*
