Betreff: Re: Last Call: <draft-trammell-ipfix-tcpcontrolbits-revision-04.txt> (Revision of the tcpControlBits IPFIX Information Element) to Informational RFC
hi Michael,
Thanks for the comment, and apologies for the delayed reply; I've
replaced this wording in an upcoming -05 revision with:
Each of the three bits (0x800, 0x400, and 0x200) which are
reserved for future use in [RFC0793] SHOULD be exported as
observed in the TCP headers of the packets of this Flow.
Cheers,
Brian

Strictly speaking, this terminology differs slightly to RFC 793 and the very well-known figure depicting the TCP header.
