		// summary:
		//		A layout container that splits the window horizontally or
		//		vertically.
		// description:
		//		FixedSplitter is a very simple container widget that layouts its
		//		child DOM nodes side by side either horizontally or
		//		vertically. An example usage of this widget would be to realize
		//		the split view on iPad. There is no visual splitter between the
		//		children, and there is no function to resize the child panes
		//		with drag-and-drop. If you need a visual splitter, you can
		//		specify a border of a child DOM node with CSS.
		//
		//		FixedSplitter has no knowledge of its child widgets.
		//		dojox/mobile/Container (formerly known as FixedSplitterPane),
		//		dojox/mobile/Pane, or dojox/mobile/ContentPane can be used as a
		//		child widget of FixedSplitter.
		//
		//		- Use dojox/mobile/Container if your content consists of ONLY
		//		  Dojo widgets.
		//		- Use dojox/mobile/Pane if your content is an inline HTML
		//		  fragment (may or may not include Dojo widgets).
		//		- Use dojox/mobile/ContentPane if your content is an external
		//		  HTML fragment (may or may not include Dojo widgets).
		//
		// example:
		//	|	<div data-dojo-type="dojox.mobile.FixedSplitter" orientation="H">
		//	|		<div data-dojo-type="dojox.mobile.Pane"
		//	|			style="width:200px;border-right:1px solid black;">
		//	|			pane #1 (width=200px)
		//	|		</div>
		//	|		<div data-dojo-type="dojox.mobile.Pane">
		//	|			pane #2
		//	|		</div>
		//	|	</div>

		// orientation: String
		//		The direction of split. If "H" is specified, panes are split
		//		horizontally. If "V" is specified, panes are split vertically.
		orientation: "H",

		// variablePane: Number
		//		The index of a pane that fills the remainig space.
		//		If -1, the last child pane fills the remaining space.
		variablePane: -1,

		// screenSizeAware: Boolean
		//		If true, dynamically load a screen-size-aware module.
