      "This YANG module defines the CoS to Frame Map. A combination of
cos and color yields a pcp and dei or ip-dscp or mpls-tc.
Additionally, for some forwarding-plane architectures, this module also
defines the CoS to Queue Map. CoS yields a Queue Number and also a WRED
curve number for green or yellow frames.";
