I have reviewed this document as part of the Ops area directorate's ongoing
effort to review all IETF documents being processed by the IESG.  These
comments were written primarily for the benefit of the Ops area directors.
Document editors and WG chairs should treat these comments just like any other
last-call comments.

This document is well written and I believe it is ready for publication.
However I have a few comments on the latest version v-05.

93	   This document specifies new IP Flow Information Export (IPFIX)
94	   Information Elements (IEs) to solve a set of issues encountered with

nits: reference to RFC7011 and RFC7012 should be added.

170	   The definition of the ipv6ExtensionHeaders IE is updated in
171	   [I-D.ietf-opsawg-ipfix-fixes] to address some of the issues listed in
172	   Section 1.1.  Because some of these limitations can't be addressed by
173	   simple updates to ipv6ExtensionHeaders, this section specifies a set
174	   of new IEs to address all the ipv6ExtensionHeaders IE limitations.

Question: I'm confused here. Do the new IEs proposed in this document address
all the issues? If so, why are the updates to ipv6ExtensionHeaders needed? Some
clarifications will be helpful.
