This read-create RowStatus object governs creation, activation, and deletion of policy-to-class reference rows, effectively adding or removing a class map from a policy map. An admin uses this to attach a previously defined class map to a policy map, or detach it without needing to redefine the class map itself. For example, to remove the 'VOICE' class map from a policy without deleting the class map, since it might be reused in another policy, the admin sets this reference row's status to destroy.
