+  description: Describes how the charging process is controlled.
+               DEACTIVATED means that charging and discharging is deactivated, nothing will happen if charger is connected.
+               AUTOMATIC means charging will be initiated as soon as charger is connected.
+               TRIGGERED means charging will be initiated when triggered by user.
+               TIMER means charging is timer-based.
+               PROFILE means charging is controlled by profile downloaded to vehicle.
+               EXTERNAL_ENTITY means charging/discharging is controlled by the external entity connected to the vehicle.
+               This includes GRID-controlled charging (e.g. ISO 15118), but also other cases where vehicle is
+               connected to an arbitrary load that is powered by the vehicle.

-  comment:     The mechanism to provide a profile to the vehicle is currently not covered by VSS.
+  deprecation: V4.1 - MANUAL and GRID are deprecated, please use AUTOMATIC/TRIGGERED or EXTERNAL_ENITY instead.
+  comment:     EXTERNAL_ENTITY is the only mode where discharge may occur.
