Yeah.  You're adding a new fundamental state to the protocol; it's not
enough to bury that in the description of a message format.  I don't
think a whole lot of new verbiage is needed, but the COPY section needs
to point out that this is a different state that allows both send and
receive, and explain what the conditions are for getting into and out of
that state.
