* **secondaryGroupExistingQueue**: the app is placed into a queue with a name that matches a secondary group of the user who submitted it. The first secondary group that matches a configured queue will be selected. Periods in group names will be replaced with "\_dot\_", i.e. a user with "one.two" as one of their secondary groups would be placed into the "one\_dot\_two" queue, if such a queue exists.
* **nestedUserQueue**: the app is placed into a queue with the name of the user under the queue suggested by the nested rule. This is similar to ‘user’ rule,the difference being in 'nestedUserQueue' rule,user queues can be created under any parent queue, while 'user' rule creates user queues only under root queue. Note that nestedUserQueue rule would be applied only if the nested rule returns a parent queue.One can configure a parent queue either by setting 'type' attribute of queue to 'parent' or by configuring at least one leaf under that queue which makes it a parent. See example allocation for a sample use case.
