      "Waveserver Platform Data Model
       Migrated from Waveserver Classic R1.4 YANG model.
       Updated namespace to 'ciena-waveserver'.
       Added scp server support (from WS 1.5).
       Remove bandplan, front-display, fcs-error-forwarding, low-power-mode as not supported on WS Ai R1.0.
       Updated xftp-config/tftp 'dhcp-host-name' and 'current-host-name' to be config false.
       Added 'default-settings' container with leafs to configure 'conditioning-type' and 'conditioning-holdoff' system defaults.
       Added 'grpc-server-state' and 'scp-server-state' to server-config container.
       Combined several boolean leafs in 'server-settings-group' into a single enum.";
