Hi Wes, Thank you for the review.
The changes to take into account your review can be seen at: https://github.com/boucadair/ipfix-tcpoptions-and-v6eh/commit/8bd7d7f92180a8eeaeb9ce13c0028a5c698b1738 Please see inline for more context.

[Med] Any observed ID must be reported independent of whether the value is registered or not.

[Med] Added a reference to the IANA registry as that is the normative ref for these IEs as per the following from RFC7012: [IANA-IPFIX] is now the normative reference for IPFIX Information Elements. When [RFC5102] was published, it defined, in its Section 5, the initial contents of that registry. > > - Section 1.1, "do no correspond" -> "do not correspond" [Med] Fixed > ____________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
