The draft goes back to the originating body, sometimes bouncing back and forth if the orginating body cannot resolve the unresolved issues. Now something about the composition of the delegations. There were about 2500 people registered for WRC-97 with about a thousand in attendance at any given time. Not all countries are represented. There are also about twenty international observer delegations.
Some delegations are small, and some are huge.
The reason for the large delegations is that there are many sessions going on in parallel. Also, there are strong commercial interests at work. A big company may have several people at the WRC to represent their interest at a key session which may occupy no more than half a day. Let's take Canada as a typical average example. There were 46 persons on the delegation.
