The Content Token must be released by the participant that is currently holding it before
it can be re-allocated.
After release, the Content Token is allocated to the participant that most recently
requested it.
The Content Token can be withdrawn from a conference participant by using the RMX
web client only if the highest level master conference is running on the RMX unit.
