+  Defines the all available volume groups for volume control in a car.
+  One can overlay this configuration to customize the groups.
+
+  This configuration will be populated by CarAudioService and
+  surfaced to Car Settings App and/or other volume control interfaces.
+
+  Certain constraints applied to this configuration
+    - One context should not appear in two groups
+    - All contexts are assigned
+    - One bus should not appear in two groups
+    - All gain controllers (set on each bus) in one group have same step value
+
+  It is fine that there are buses that do not appear in any group, those buses
+  may be reserved for other usages.
+
+  Important note: when overlaying this configuration,
+  make sure the resources are in the same package as CarAudioService.
