        // description:
        //              Currently for markup only. All controls should reside as child
        //              nodes within the Player node. 'controlType' is used to determine
        //              the placement of the control. If no type or an unrecognized type
        //              is used, it will be left-aligned in the same row as the volume.
        //
        //              Note:
        //              Be sure to use 'controlType' as a node attribute. It is not a
        //              property of the widget.
        // example:
        //              |       <div dojoType="dojox.av.widget.Player" playerWidth="100%">
    //          |               <div controlType="video" initialVolume=".1"
