RE: [ipfix-protocol] new version of the IPFIX protocol draft: draft-ietf-ipfix-protocol-12.txt

What is the max length of a fixed length field ? Is it 65534 ? Does that make sense as the max length of an IPFIX msg is 65535 ?
At large, in the future IPFIX will need to define new kind of field types. The current definition of 'Field Length' must be prepared for that. I propose to reserve the MSB of 'Field Length' for future usage.

Objet : [ipfix-protocol] new version of the IPFIX protocol draft: draft-ietf-ipfix-protocol-12.txt
I just posted a new version of the IPFIX protocol draft, with the feedback from Paul Aitken's thorough review.
Here are the list of changes:
- Some cross references were wrong
- Flow Record definition exactly similar to the one in [IPFIX-ARCH]
- Template definition exactly similar to the one in [IPFIX-ARCH]
- As deduced from section 9, the source ID definition now contains: the source ID MUST NOT be 0
- The Field Length is completed with: The value 65535 is reserved for variable length Information Element (see section 7). The Field Length MAY NOT 0.
- one mistake corrected in figure O
- correction: In most cases the length of the Information Element will be less than 256 255 octets.
- correction: The IPFIX Message Header 16-bit Length field limits the length of a IPFIX Message to 65536 65535 octets including the header.
- section 10.4.1.2 referred to SCTP while it was a TCP section. Ooops ;) BTW, the TCP sections now speaks of TCP connection as opposed to TCP association
- added the 2 sentences
- A lot of editorial corrections and improvements
