tcpm,

This new revision is primarily a refresh to head-off impending expiry.

Summary of diffs:

* Explained:
                 Table 1 does not imply any obligation to set any packet to
                 ECT.  ECN++ removes the restrictions that RFC 3168 
places against
                 setting ECT on these types of packets, and an 
implementation would
                 normally be expected to take advantage of this, but it 
does not have to.

* Deleted 'experimental' from description of AccECN since the WG decided 
it ought to be intended for Proposed Std.

All the other diffs are artefacts of the switch from V2 to V3 RFC XML.

Cheers

Bob
