+    <!-- The default theme for apps that target API level 14 and higher.
+         <p>The DeviceDefault themes are aliases for a specific device’s native look and feel. The
+         DeviceDefault theme family and widget style family offer ways for you to target your app
+         to a device’s native theme with all device customizations intact.</p>
+         <p>For example, when you set your app's {@code targetSdkVersion} to 14 or higher, this
+         theme is applied to your application by default. As such, your app might appear with the
+         {@link #Theme_Holo Holo} styles on one device, but with a different set of styles on
+         another device. This is great if you want your app to fit with the device's native look and
+         feel. If, however, you prefer to keep your UI style the same across all devices, you should
+         apply a specific theme such as {@link #Theme_Holo Holo} or one of your own design. For more
+         information, read <a
+         href="http://android-developers.blogspot.com/2012/01/holo-everywhere.html">Holo
+         Everywhere</a>.</p>
+         <p>Styles used by the DeviceDefault theme are named using the convention
+         Type.DeviceDefault.Etc (for example, {@code Widget.DeviceDefault.Button} and
+         {@code TextAppearance.DeviceDefault.Widget.PopupMenu.Large}).</p>
