I believe the draft needs one more spin in order to be precise
about the number of bytes included in the upper layer header.
Consider that in addition to the common transport headers,
and ICMPv6, any protocol number defined in the IANA registry
that is not an extension header might in theory occur as the
final "next header". The phrasing in the draft at present does
not tell a programmer what to do in the general case:
Note: If there is an upper layer header, only the header (and
not its payload) are considered part of the "entire IPv6 header
chain".
