This document has been reviewed as part of the transport area review team's ongoing effort to review key IETF documents. These comments were written primarily for the transport area directors, but are copied to the document's authors and WG to allow them to address any issues raised and also to the IETF discussion list for information. When done at the time of IETF Last Call, the authors should consider this review as part of the last-call comments they receive. Please always CC tsv-art@ietf.org if you reply to or forward this review. This document does some housekeeping on the IPFIX Information Elements registry, to conform to a standard table format and fix other minor errors. There are no transport protocol implications. The reference to the port registry is correct. It might be good for PortRangeStart and PortRangeEnd to clarify that the linked registry is not just for TCP, but also UDP, SCTP, and DCCP.
