                    </svc-bandwidth>

Notes
-----
* Note 1: cos-id must be included as per the following:

                  leaf cos-id {
                    when "derived-from-or-self(../type, "
                       + "'l2vpn-svc:bw-per-cos')" {
                      description
                        "Relevant when the bandwidth type is set to
                         'bw-per-cos'.";
                    }
                    type uint8;
                    description
                      "Identifier of the CoS, indicated by DSCP or a
                       CE-VLAN CoS (802.1p) value in the service frame.
                       If the bandwidth type is set to 'bw-per-cos',
                       the CoS ID MUST also be specified.";
                  }

* Note 2: More changes are needed because the current structure does not allow to specify multiple cos-ids.
