Child Service Policy Allowed Under Priority Class

in Cisco IOS Release 12.2(31)SB2. This feature allows you to attach a child policy with non-queuing
features to a priority class. The priority class must be in the middle-level policy of a three-level
hierarchical policy or in the parent policy of a two-level hierarchical policy (nested policy).
