Magnus and Dan,

thanks for the review.

Magnus, you are right, I have removed the first full paragraph
about "security properties" from Security Considerations
from my git version as the security properties of EdDSA
are better described in Normative references anyway.

https://gitlab.labs.nic.cz/labs/ietf/commit/7b52c8e2bbe44042a279a81b960270fdd103d9a2

Dan,

good catches, I fixed the nits in the git:

https://gitlab.labs.nic.cz/labs/ietf/commit/bbfc7ce43fb1f46c91fb7f5de564d907d035aadf

I would be happy to upload next revision after Last Call
is finished or just let the RFC editors to fix it.

Cheers,
--
