Description of Working Group:

The Transport Area receives occasional proposals for the development 
and publication of RFCs dealing with Transport topics, but for which 
the required work does not rise to the level where a new working group 
is justified, yet the topic does not fit with an existing working 
group, and a single BOF would not provide the time to ensure a mature 
proposal. The tsvwg will serve as the forum for developing these types 
of proposals.

The tsvwg mailing list will be used to discuss the proposals as they 
arise. The working group will meet if there are one or more active 
proposals that require discussion.

The working group milestones will be updated as needed to reflect the
proposals currently being worked on and the target dates for their
completion. New milestones will be first reviewed by the IESG. The
working group will be on-going as long as the ADs believe it serves a
useful purpose.
