[dmarc-ietf] AD review of draft-ietf-dmarc-arc-protocol-18

[Alexey Melnikov <[e-mail]>]

I've reviewed recent changes and they look like an improvement over 
earlier versions. I have a few minor comments:

1) I think several references need to be reclassified as Normative:

    [I-D-7601bis]
               Kucherawy, M., "Message Header Field for Indicating
               Message Authentication Status", February 2018,
               <https://datatracker.ietf.org/doc/
               draft-ietf-dmarc-rfc7601bis/>.

I am pretty sure this document is a Normative reference for ARC. Please 
move it to Normative references.

    [draft-levine-eaiauth]
               Levine, J., "E-mail Authentication for Internationalized
               Mail", August 2018, <https://tools.ietf.org/html/
               draft-levine-appsarea-eaiauth-03>.

This also looks like a Normative reference. E.g. see the text in Section 
4.1.4 of this draft.

2) I am glad that broken examples from Appendix B were removed, but I 
would like to have some examples in the document. Is somebody working on 
generating these?

Thank you,

Alexey
