 //		Quality Of Service Qos Configuration Flexibility
+//			Quality of service (QoS) configuration flexibility: This attribute reports whether various MEs
+//			in the ONU are fixed by the ONU's architecture or whether they are configurable. For backward
+//			compatibility, and if the ONU does not support this attribute, all such attributes are
+//			understood to be hard-wired. (R) (optional) (2-bytes)
+//
+//			Discussion:
+//
+//			To allow for the possibility that the OLT does not support flexible configuration, the ONU
+//			vendor must assure that the priority queues and traffic schedulers are configured in a
+//			meaningful and useful way by factory default, and that this default configuration is restored
+//			upon ONU initialization and MIB reset. The specifics of such a configuration are beyond the
+//			scope of this Recommendation.
+//
 //			The ME ID of both the T-CONT and traffic scheduler contains a slot number. Even when attributes
 //			in the above list are RW, it is never permitted to change the slot number in a reference. That
 //			is, configuration flexibility never extends across slots. It is also not permitted to change the
 //			directionality of an upstream queue to downstream or vice versa.
 //
 //		Priority Queue Scale Factor
+//			If this optional attribute is implemented, it specifies the scale factor of several attributes
+//			of the priority queue ME of clause-9.2.10. The default value of this attribute is 1. (R, W)
+//			(optional) (2-bytes)
+//
 //			NOTE 3 - Some legacy implementations may take the queue scale factor from the GEM block length
 //			attribute of the ANI-G ME. That option is discouraged in new implementations.
