+* Note that setting this property alone should not trigger any change.
+* Audio routing should be changed only when AUDIO_FOCUS property is set. Note that
+* this property allows passing custom value as long as it is defined in config_string.
+* This allows supporting non-standard routing options through this property.
+* It is recommended to use separate name space for custom property to prevent conflict in future
+* android releases.
+* Enabling each external routing option is done by enabling each bit flag for the routing.
+* This property can support up to 128 external routings.
+* To give full flexibility, there is no standard definition for each bit flag and
+* assigning each big flag to specific routing type is decided by config_string.
+* config_string has format of each entry separated by ','
+* and each entry has format of bitFlagPositon:typeString[:physicalStreamNumber].
+*  bitFlagPosition: represents which big flag will be set to enable this routing. 0 means
+*    LSB in int32_array[0]. 31 will be MSB in int32_array[0]. 127 will MSB in int32_array[3].
+*  typeString: string representation of external routing. Some types are already defined
+*    in VEHICLE_PROPERTY_AUDIO_EXT_ROUTING_SOURCE_* and use them first before adding something
+*    custom. Applications will find each routing using this string.
+*  physicalStreamNumber: This part is optional and represents physical stream to android
+*    which will be disabled when this routing is enabled. If not specified, this routing
+*    should not affect physical streams to android.
+* As an example, let's assume a system with two physical streams, 0 for media and 1 for
+* nav guidance. And let's assume external routing option of am fm radio, external navigation
+* guidance, satellite radio, and one custom. Let's assume that radio and satellite replaces
+* physical stream 0 and external navigation replaces physical stream 1. And bit flag will be
+* assigned in the order listed above. This configuration will look like this in config_string:
+*  "0:RADIO_AM_FM:0,1:EXT_NAV_GUIDANCE:1,2:RADIO_SATELLITE:0,3:com.test.SOMETHING_CUSTOM"
