+   <!-- The bounding path of the cutout region of the main built-in display.
+         Must either be empty if there is no cutout region, or a string that is parsable by
+         {@link android.util.PathParser}.
+         The path is assumed to be specified in display coordinates with pixel units and in
+         the display's native orientation, with the origin of the coordinate system at the
+         center top of the display.
+         To facilitate writing device-independent emulation overlays, the marker `@dp` can be
+         appended after the path string to interpret coordinates in dp instead of px units.
+         Note that a physical cutout should be configured in pixels for the best results.
+         Example for a 10px x 10px square top-center cutout:
+                <string ...>M -5,0 L -5,10 L 5,10 L 5,0 Z</string>
+         Example for a 10dp x 10dp square top-center cutout:
+                <string ...>M -5,0 L -5,10 L 5,10 L 5,0 Z @dp</string>
