Приоритеты в xmpp

Here are the basic rules for priorities:

• The resource with the highest priority at any given time will be the one which receives incoming messages.
  
• If two or more resources have the same priority, all resources with said priority will receive incoming messages.
  
• If all connected resources have a negative priority, incoming messages will be queued server-side until one of the resources resets priority to be positive.
