Document: draft-ietf-opsawg-ipfix-tcpo-v6eh-11 Reviewer: Joel Halpern Review Date: 2024-05-02 IETF LC End Date: 2024-05-10 IESG Telechat date: Not scheduled for a telechat Summary: This document is ready for publication as a Proposed Standard RFC Major issues: None Minor issues: The document uses the phrasing "If several extension header chains are observed in a Flow" in several places. While I believe I figured out what was intended, it caused me difficulty. Assuming I understood the intent, I would suggest defining a term "flow with varying header chain" as "a flow wherein different packets in the flow have a different sequence of extension header types codes." And then use that term in the suitable places in the document. Nits/editorial comments: None
