+    <!-- The number of vibration intensity levels supported by the device.
 
+         Note that this should correspond to the ability to vary the vibration amplitude, with
+         enough dynamic range to have at least as many distinct intensity levels as defined here.
+
+         Supported values are 1, 2, 3. If '1', the settings app will use a toggle for the settings,
+         otherwise a slider. If '3', the settings app maps intensities directly to the levels
+         supported by the Vibrator HAL APIs. If '2', then the levels will be mapped to
+         VIBRATION_INTENSITY_LOW and VIBRATION_INTENSITY_HIGH, which gives the most range for
+         scaling vibrations. The medium intensity will be skipped.
+
+         The default intensity values are configured at
+         frameworks/base/core/res/res/values/config.xml's config_default[type]VibrationIntensity.
+         Make sure that each default intensity value is consistent with the supported levels set
+         here. If this settings supports only 2 levels, for example, then the default intensity
+         should be either LOW (1) or HIGH (3).
