Hi,

I have been selected as the Operational Directorate (opsdir) reviewer for this Internet-Draft. 

The Operational Directorate reviews all operational and management-related Internet-Drafts to ensure alignment with operational best practices and that adequate operational considerations are covered.

A complete set of _"Guidelines for Considering Operations and Management in IETF Specifications"_ can be found at https://datatracker.ietf.org/doc/draft-opsarea-rfc5706bis/.

While these comments are primarily for the Operations and Management Area Directors (Ops ADs), the authors should consider them alongside other feedback received.


Summary: Overall this makes sense and seems fine to me. There are a couple of minor nits or things I think could be clarified.

It's a little unclear if the intent is to say 'middle boxes MUST NOT' modify the Reflect All message. In the beginning (end of #1) it says middles boxes are not intended while later (#4 before the picture) it says 'must not modify'. I assume this should be 'MUST NOT' consistently?

Is the intent of Reflect All to include all headers only (as the picture implies) or all headers and potentially more of the original request object as some of the language implies? I don't see a major issue with either but think this could be clearer and more consistent.


Regards,
    Niclas
