  * sensor types are specific to an OEM and can't be exposed in the SDK.
  * These types must start at SENSOR_TYPE_DEVICE_PRIVATE_BASE.
- *
- * All sensors defined outside of the device private range must correspond to
- * a type defined in this file, and must satisfy the characteristics listed in
- * the description of the sensor type.
- *
- * Starting with version SENSORS_DEVICE_API_VERSION_1_2, each sensor also
- * has a stringType.
- *  - StringType of sensors inside of the device private range MUST be prefixed
- *    by the sensor provider's or OEM reverse domain name. In particular, they
- *    cannot use the "android.sensor" prefix.
- *  - StringType of sensors outside of the device private range MUST correspond
- *    to the one defined in this file (starting with "android.sensor").
- *    For example, accelerometers must have
- *      type=SENSOR_TYPE_ACCELEROMETER and
- *      stringType=SENSOR_STRING_TYPE_ACCELEROMETER
- *
- * When android introduces a new sensor type that can replace an OEM-defined
- * sensor type, the OEM must use the official sensor type and stringType on
- * versions of the HAL that support this new official sensor type.
- *
- * Example (made up): Suppose Google's Glass team wants to surface a sensor
- * detecting that Glass is on a head.
- *  - Such a sensor is not officially supported in android KitKat
- *  - Glass devices launching on KitKat can implement a sensor with
- *    type = 0x10001 and stringType = "com.google.glass.onheaddetector"
- *  - In L android release, if android decides to define
- *    SENSOR_TYPE_ON_HEAD_DETECTOR and STRING_SENSOR_TYPE_ON_HEAD_DETECTOR,
- *    those types should replace the Glass-team-specific types in all future
- *    launches.
- *  - When launching glass on the L release, Google should now use the official
- *    type (SENSOR_TYPE_ON_HEAD_DETECTOR) and stringType.
- *  - This way, all applications can now use this sensor.
