I would like to remind you that the CSCP is an extension of the BFCP.
So, CSCP can re-used some operations already defined in BFCP, for
instance, the "Hello" operation defined in the BFCP that checks the
liveness of the focus.

As well, I would like to remind you that the CSCP is following the same
general protocol requirements that the Floor Control Protocol defined in
RFC 4376. For instance, REQ-GEN-1:

"Bandwidth and terminal limitations SHOULD be taken into account in
order to ensure that floor control can be efficiently used in mobile
environments."

The CCCP ping is a liveness check similar to the ill-fated SIP PING
discussions. It specifically checks for application-level liveness of
the conference state at the Focus. There are some interesting failover
cases that could benefit from this  --- there may also be much better or
simpler solutions. I'm fine with cutting this from the initial list of
operations.

The CCCP cancel command is similar to a SIP CANCEL which we thought
might be useful to terminate long commands (addUser for example). In
retrospect, we might want to cut this operation for now until we have a
better handle on the other operations.

As clarification, what I posted was a straight union of the operations
from all four proposals, not what I thought was a good set of
operations. This isn't likely to make sense without some paring.
However, at least *some* one thought that each of the operations was a
good idea.

Consider the construct:
  <foo bar="baz" />

In XML, "foo" is the element, and "bar" is an attribute of that element.

See the CSCP draft for more information.
