I hope Sally and/or Mark speak up here. I'm not sure whether
RFC3448bis is considered in its early stages, or should be implemented
right away, or what....
Formally, RFC 3448 and RFC 3448 Errata are the official specification
for TFRC,
and RFC 4342 is an official specification for CCID 3, which uses some
modifications to TFRC that are described only in RFC 4342.
Formally, RFC3448bis is an internet-draft, work-in-progress, with no
official
standing other than as a work item of the DCCP working group.
Informally, I think it would be wise for TFRC implementers to be aware
of,
and contributing to, RFC3448bis.
