I am sorry, my response was too quick and because I currently don't
work with CCXML at all, I confused the Dialog object with dialog commands,
and I confused the latest specification with earlier ones.

But you are right, I think that conferenceid/connectionid in Dialog object 
is
not needed because there are input and output properties. The dialogid
property of the Connection object is also not needed for the same reason,
or at least the specification should state that it drives the media stream 
to
the connection.
