      "Waveserver Platform Data Model
       Migrated from Waveserver Classic R1.4 YANG model.
       Updated namespace to 'ciena-waveserver'.
       Changed 'xcvrs' list key from 'xcvr-index' (integer type) to 'xcvr-id' (string type) to accommodate '<slot>-<port>' format.
       Changed 'child-ptp-id' type from integer to string to accommodate '<slot>-<port>' format.
       Changed 'power-state' enum values to use common typedef.
       Renamed 'channels' to 'lanes'.
       Updated description strings, fixed several lint errors/warnings.
       Updated 'operational-state' enum values.
       Removed 'description' attribute from 'id' container.
       Removed 'xcvr-delete' RPC (deletes will be handled via native delete operation instead).";
