[XCON] Comment on floor control requirements

In draft-koskelainen-xcon-floor-control-req-00 there are hints that some sort of queue exists when the number of participants requesting the floor exceeds the number of participants allows simultaneous use of the floor.

For example REQ-10 refers to the number of simultaneous floor holders, and REQ-11 refers to passing the floor to the next in line after a time interval.

It would appear to me that this queuing needs to be more extensively discussed in the above requirements document. 

Firstly REQ-11 implies that the queue is first in, first out (and I stress that this is an implication), whereas in real life certain users may preempt others in the queue. 

Secondly it would appear to be appropriate to have requirements for the floor control chair to have requirements for manipulating the queue, e.g. to designate the order of obtaining the floor, to clear the queue and so on.

Additionally, perhaps other participants may also require visibility of the queue.

My proposal would therefore to update the draft to explicitly define this queue concept, and then to revise the requirements to reflect the existence of the queue, and add requirements for the manipulation of the queue.
