+     * Additional rules for mapping a zoned HVAC property (except
+     * HVAC_MAX_DEFROST_ON) to AreaIDs:
+     *  - Every seat in VehicleAreaSeat that is available in the car, must be
+     *    part of an AreaID in the AreaID array.
+     *
+     * Example 1: A car has two front seats (ROW_1_LEFT, ROW_1_RIGHT) and three
+     *  back seats (ROW_2_LEFT, ROW_2_CENTER, ROW_2_RIGHT). There are two
+     *  temperature control units -- driver side and passenger side.
+     *   - A valid mapping set of AreaIDs for HVAC_TEMPERATURE_SET would be a
+     *     two element array:
+     *      - ROW_1_LEFT  | ROW_2_LEFT
+     *      - ROW_1_RIGHT | ROW_2_CENTER | ROW_2_RIGHT
+     *   - An alternative mapping for the same hardware configuration would be:
+     *      - ROW_1_LEFT  | ROW_2_CENTER | ROW_2_LEFT
+     *      - ROW_1_RIGHT | ROW_2_RIGHT
+     *  The temperature controllers are assigned to the seats which they
+     *  "most influence", but every seat must be included exactly once. The
+     *  assignment of the center rear seat to the left or right AreaID may seem
+     *  arbitrary, but the inclusion of every seat in exactly one AreaID ensures
+     *  that the seats in the car are all expressed and that a "reasonable" way
+     *  to affect each seat is available.
+     *
+     * Example 2: A car has three seat rows with two seats in the front row (ROW_1_LEFT,
+     *  ROW_1_RIGHT) and three seats in the second (ROW_2_LEFT, ROW_2_CENTER,
+     *  ROW_2_RIGHT) and third rows (ROW_3_LEFT, ROW_3_CENTER, ROW_3_RIGHT). There
+     *  are three temperature control units -- driver side, passenger side, and rear.
+     *   - A reasonable way to map HVAC_TEMPERATURE_SET to AreaIDs is a three
+     *     element array:
+     *     - ROW_1_LEFT
+     *     - ROW_1_RIGHT

+     * Defines a request to switch the foreground Android user.
+     *
+     * This property is used primarily by the Android System to inform the HAL that the
+     * current foreground Android user is switching, but it could also be used by the HAL to request
+     * the Android system to switch users - the
+     *
+     * When the request is made by Android, it sets a VehiclePropValue and the HAL must responde
+     * with a property change event; when the HAL is making the request, it must also do it through
+     * a property change event (the main difference is that the request id will be positive in the
+     * former case, and negative in the latter; the SwitchUserMessageType will also be different).
+     *
+     * The format of both request is defined by SwitchUserRequest and the format of the response
+     * (when needed) is defined by SwitchUserResponse. How the HAL (or Android System) should
+     * proceed depends on the message type (which is defined by the SwitchUserMessageType
+     * parameter), as defined below.
+     *
+     * 1.LEGACY_ANDROID_SWITCH
+     * -----------------------
+     *
+     * Called by the Android System to indicate the Android user is about to change, when the change
+     * request was made in a way that is not integrated with the HAL (for example, through
+     * adb shell am switch-user).
+     *
+     * The HAL can switch its internal user once it receives this request, but it doesn't need to
+     * reply back to the Android System. If its internal user cannot be changed for some reason,
+     * then it must wait for the SWITCH_USER(type=ANDROID_POST_SWITCH) call to recover
+     * (for example, it could issue a SWITCH_USER(type=VEHICLE_REQUEST) to switch back to
+     * the previous user), but ideally it should never fail (as switching back could result in a
+     * confusing experience for the end user).
+     *
+     * For example, if the system have users (0, 10, 11) and it's switching from 0 to 11 (where none
+     * of them have any special flag), the request would be:
+     *
+     * int32[0]:  42  // request id
+     * int32[1]:  1   // SwitchUserMessageType::LEGACY_ANDROID_SWITCH
+     * int32[2]:  11  // target user id
+     * int32[3]:  0   // target user flags (none)
+     * int32[4]:  10  // current user
+     * int32[5]:  0   // current user flags (none)
+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // user #0 (Android user id 0)
+     * int32[8]:  0   // flags of user #0 (none)
+     * int32[9]:  10  // user #1 (Android user id 10)
+     * int32[10]: 0   // flags of user #1 (none)
+     * int32[11]: 11  // user #2 (Android user id 11)
+     * int32[12]: 0   // flags of user #2 (none)
+     *
+     * 2.ANDROID_SWITCH
+     * ----------------
+     * Called by the Android System to indicate the Android user is about to change, but Android
+     * will wait for the HAL's response (up to some time) before proceeding.
+     *
+     * The HAL must switch its internal user once it receives this request, then respond back to
+     * Android with a SWITCH_USER(type=VEHICLE_RESPONSE) indicating whether its internal
+     * user was switched or not (through the SwitchUserStatus enum).
+     *
+     * For example, if Android has users (0, 10, 11) and it's switching from 10 to 11 (where
+     * none of them have any special flag), the request would be:
+     *
+     * int32[0]:  42  // request id
+     * int32[1]:  2   // SwitchUserMessageType::ANDROID_SWITCH
+     * int32[2]:  11  // target user id
+     * int32[3]:  0   // target user flags (none)
+     * int32[4]:  10  // current user
+     * int32[5]:  0   // current user flags (none)
+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // 1st user (user 0)
+     * int32[8]:  1   // 1st user flags (SYSTEM)
+     * int32[9]:  10  // 2nd user (user 10)
+     * int32[10]: 0   // 2nd user flags (none)
+     * int32[11]: 11  // 3rd user (user 11)
+     * int32[12]: 0   // 3rd user flags (none)
+     *
+     * If the request succeeded, the HAL must update the property with:
+     *
+     * int32[0]: 42  // request id
+     * int32[1]: 3   // messageType = SwitchUserMessageType::VEHICLE_RESPONSE
+     * int32[2]: 1   // status = SwitchUserStatus::SUCCESS
+     *
+     * But if it failed, the response would be something like:
+     *
+     * int32[0]: 42   // request id
+     * int32[1]: 3    // messageType = SwitchUserMessageType::VEHICLE_RESPONSE
+     * int32[2]: 2    // status = SwitchUserStatus::FAILURE
+     * string: "108-D'OH!" // OEM-specific error message
+     *
+     * 3.VEHICLE_RESPONSE
+     * ------------------
+     * Called by the HAL to indicate whether a request of type ANDROID_SWITCH should proceed or
+     * abort - see the ANDROID_SWITCH section above for more info.
+     *
+     * 4.VEHICLE_REQUEST
+     * ------------------
+     * Called by the HAL to request that the current foreground Android user is switched.
+     *
+     * This is useful in situations where Android started as one user, but the vehicle identified
+     * the driver as another user. For example, user A unlocked the car using the key fob of user B;
+     * the INITIAL_USER_INFO request returned user B, but then a face recognition subsubsystem
+     * identified the user as A.
+     *
+     * The HAL makes this request by a property change event (passing a negative request id), and
+     * the Android system will response by issue an ANDROID_POST_SWITCH call which the same
+     * request id.
+     *
+     * For example, if the current foreground Android user is 10 and the HAL asked it to switch to
+     * 11, the request would be:
+     *
+     * int32[0]: -108  // request id
+     * int32[1]: 4     // messageType = SwitchUserMessageType::VEHICLE_REQUEST
+     * int32[2]: 11    // Android user id
+     *
+     * If the request succeeded and Android has 3 users (0, 10, 11), the response would be:
+     *
+     * int32[0]: -108 // request id
+     * int32[1]:  5   // messageType = SwitchUserMessageType::ANDROID_POST_SWITCH
+     * int32[2]:  11  // target user id
+     * int32[3]:  0   // target user id flags (none)
+     * int32[4]:  11  // current user
+     * int32[5]:  0   // current user flags (none)
+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // 1st user (user 0)
+     * int32[8]:  0   // 1st user flags (none)
+     * int32[9]:  10  // 2nd user (user 10)
+     * int32[10]: 4   // 2nd user flags (none)
+     * int32[11]: 11  // 3rd user (user 11)
+     * int32[12]: 3   // 3rd user flags (none)
+     *
+     * Notice that both the current and target user ids are the same - if the request failed, then
+     * they would be different (i.e, target user would be 11, but current user would still be 10).
+     *
+     * 5.ANDROID_POST_SWITCH
+     * ---------------------
+     * Called by the Android System after a request to switch a user was made.
+     *
+     * This property is called after switch requests of any type (i.e., LEGACY_ANDROID_SWITCH,
+     * ANDROID_SWITCH, or VEHICLE_REQUEST) and can be used to determine if the request succeeded or
+     * failed:
+     *
+     * 1. When it succeeded, it's called when the Android user is in the unlocked state and the
+     *    value of the current and target users ids in the response are the same. This would be
+     *    equivalent to receiving an Intent.ACTION_USER_UNLOCKED in an Android app.
+     * 2. When it failed it's called right away and the value of the current and target users ids
+     *    in the response are different (as the current user didn't change to the target).
+     * 3. If a new switch request is made before the HAL responded to the previous one or before
+     *    the user was unlocked, then the ANDROID_POST_SWITCH request is not made. For example,
+     *    the driver could accidentally switch to the wrong user which has lock credentials, then
+     *    switch to the right one before entering the credentials.
+     *
+     * The HAL can update its internal state once it receives this request, but it doesn't need to
+     * reply back to the Android System.
+     *
+     * Request: the first N values as defined by INITIAL_USER_INFO (where the request-specific
+     * value at index 1 is SwitchUserMessageType::ANDROID_POST_SWITCH), then 2 more values for the
+     * target user id (i.e., the Android user id that was requested to be switched to) and its flags
+     * (as defined by  UserFlags).
+     *
+     * Response: none.
+     *
+     * Example: see VEHICLE_REQUEST section above.
+     *
