Re: [Curdle] Opsdir last call review of draft-ietf-curdle-ssh-ed25519-ed448-07

Hi, Daniel,

The suggestion from Tim is a good improvement. However, it would be even better for a "standard track" document, if it gave a little bit more detailed guidance "where" and "how" a SSH implement should quota the key format that defined in this document.

Regards,

Sheng

Thanks for the suggestion Tim. That works for me. 
Yours,

Why not just reference RFC 2119 and say "Standard implementations of SSH
SHOULD implement these signature algorithms." ?
