		/**
		* Group reserved for backporting system properties introduced in a newer Android
		* release to an older Android release.
		*
		* It is recommended to map the system property ID to a backported property ID by replacing the
		* VehiclePropertyGroup, e.g. backported PERF_VEHICLE_SPEED(0x11600207) would be 0x31600207.
		*
		* When updated to a newer Android release where the property is defined as system properties,
		* the backported properties must be migrated to system properties.
		*
		* In Android system, the backported property is treated the same as a vendor defined property
		* with the same vendor permission model, a.k.a. Default required permission is
		* `android.car.Car.PERMISSION_VENDOR_EXTENSION`, or customized by
		* `SUPPORT_CUSTOMIZE_VENDOR_PERMISSION` VHAL property.
		*
		* Only applications with vendor permissions may access these backported properties.
		*
		* Vendors must also make sure this property's behavior is consistent with what is expected for
		* the backported system property, e.g. the access mode, the change mode and the config array
		* must be correct.
		*
		* When vendors define custom properties, they must use {@code VENDOR} flag, instead of
		* {@code BACKPORTED}
