- create a conference 
- terminate/remove a conference 
- invite users to the conference 
- refer users to the conference 
- remove users from the conference 
- define who is allowed to join the conference 
- define conference time information, this includes scheduled
conferences (bounded conferences, i.e. mixing start/stop time) _and_
conference lifetime (time after that the conference will be removed
resp. terminated) 
- define conditions when the conference media mixing starts/stops (e.g.
key participant or first participant joins the conference) 
- define conditions when the conference is terminated/removed (e.g. last
participant has left or has been removed from the conference or
conference creator has left the conference) 
- set some conference parameters like max-participants, conference-uri 
- define privileges for certain users (who can modify/read which
conference policy element, who can use SIP procedures to
invite/refer/remove users to/from the conference resp. more general: who
is allowed to invite/remove/refer/allow users (this would cover CPCP and
SIP procedures); who is allowed to subscribe to the conference event
package; who is allowed to subscribe to conference policy changes (XCAP
change); who can terminate the conference besides the conference
creator; etc.) 
- enumerate the media streams of the conference 
- set floor policy (floor control algorithm; maximum number of users
that can have one floor at the same time; set floor moderator; moderator
uri; etc) 
There should be some means to: 
- set general conference information (subject of the conference,
display-name, etc.) 
- create/define floors, associate media streams to floors and transfer
of BFCP parameters (goes to the "must section" if the SDP solution in
draft-camarillo-mmusic-sdp-bfcp-00 is not finished in time)
