COMMENT:
----------------------------------------------------------------------

Thanks for all the work that went into this document. I think it's very useful
to have a set of test vectors for future implementations to develop against. I
have a couple of minor comments.

---------------------------------------------------------------------------
§1:

>  Note:  Invocations of HMAC-based Extract-and-Expand Key Derivation
>     Function (HKDF) [RFC5869] are not labelled, but can be identified
>     through the use the labels used by HKDF.

This doesn't parse. Probably should say "...through the use of labels..." or
something similar.

---------------------------------------------------------------------------

§6:

>  Note that private keys for this
>  example are not included in the draft.
>
>  {client}  create an ephemeral x25519 key pair:
>
>     private key (32 octets):...

I'm not sure what to make of this. Should it say "...private RSA keys for this
example..." or something like that? It may also be useful to include a sentence
or clause explaining why the omitted private key is not useful for users of this
document.
