[openpgp] Re: I-D Action: draft-ietf-openpgp-nist-bp-comp- 00.txt

There is actually one other point worthy of discussion the authors would 
like to raise. The discussion about the use of the context parameter for 
ML-DSA and SLH-DSA in draft-ietf-openpgp-pqc concluded that the draft 
should continue using the empty string as the context parameter. The 
question that we would like to raise is whether the 
draft-ietf-openpgp-nist-bp-comp should take the same choice, or, switch 
to using a non-empty context parameter for ML-DSA.

If there should no opinion of the WG become apparent, the authors tend 
to continue using the empty context parameter.
