/**
* Packet interceptor that will intercept presence packets sent to the MUC service to indicate
* that the user wants to be a deaf occupant. A user can only indicate that he wants to be a
* deaf occupant while joining the room. It is not possible to become deaf or stop being deaf
* after the user joined the room.<p>
*
* Deaf occupants will not get messages broadcasted to all room occupants. However, they will
* be able to get private messages, presences, IQ packets or room history. To use this
* functionality you will need to send the message
* {@link MultiUserChat#addPresenceInterceptor(org.jivesoftware.smack.PacketInterceptor)} and
* pass this interceptor as the parameter.<p>
*
* Note that this is a custom extension to the MUC service so it may not work with other servers
* than Wildfire.
