  	//		Future base class for all Dijit widgets.
  	//		_Widget extends this class adding support for various features needed by desktop.
  	//
  	//		Provides stubs for widget lifecycle methods for subclasses to extend, like postMixInProperties(), buildRendering(),
  	//		postCreate(), startup(), and destroy(), and also public API methods like set(), get(), and watch().
  	//
  	//		Widgets can provide custom setters/getters for widget attributes, which are called automatically by set(name, value).
  	//		For an attribute XXX, define methods _setXXXAttr() and/or _getXXXAttr().
  	//
  	//		_setXXXAttr can also be a string/hash/array mapping from a widget attribute XXX to the widget's DOMNodes:
  	//
  	//		- DOM node attribute
  	// |		_setFocusAttr: {node: "focusNode", type: "attribute"}
  	// |		_setFocusAttr: "focusNode"	(shorthand)
  	// |		_setFocusAttr: ""		(shorthand, maps to this.domNode)
  	//		Maps this.focus to this.focusNode.focus, or (last example) this.domNode.focus
  	//
  	//		- DOM node innerHTML
  	//	|		_setTitleAttr: { node: "titleNode", type: "innerHTML" }
  	//		Maps this.title to this.titleNode.innerHTML
  	//
  	//		- DOM node innerText
  	//	|		_setTitleAttr: { node: "titleNode", type: "innerText" }
  	//		Maps this.title to this.titleNode.innerText
  	//
  	//		- DOM node CSS class
  	// |		_setMyClassAttr: { node: "domNode", type: "class" }
  	//		Maps this.myClass to this.domNode.className
  	//
  	//		If the value of _setXXXAttr is an array, then each element in the array matches one of the
  	//		formats of the above list.
  	//
  	//		If the custom setter is null, no action is performed other than saving the new value
  	//		in the widget (in this).
  	//
  	//		If no custom setter is defined for an attribute, then it will be copied
  	//		to this.focusNode (if the widget defines a focusNode), or this.domNode otherwise.
  	//		That's only done though for attributes that match DOMNode attributes (title,
  	//		alt, aria-labelledby, etc.)
  
  	// id: [const] String
  	//		A unique, opaque ID string that can be assigned by users or by the
  	//		system. If the developer passes an ID which is known not to be

  	//		used instead.

  	//
  	//		Allowed values:
  	//
  	//		1. "ltr"

  	//		|		<span data-dojo-type=subWidget>and a widget</span>
  	//		|		<i> and another plain DOM node </i>
  	//
  	//		In templated widgets, "containerNode" is set via a
  	//		data-dojo-attach-point assignment.
  	//

  	//		of the widget and the widget's DOM.
  	//		Changes to widget attributes listed in attributeMap will be
  	//		reflected into the DOM.
  	//
  	//		For example, calling set('title', 'hello')
  	//		on a TitlePane will automatically cause the TitlePane's DOM to update
  	//		with the new title.
  	//
  	//		attributeMap is a hash where the key is an attribute of the widget,
