			//			identical to the function's `rootNode` argument, though
			//			allowed to be passed in via this `options object.
			//		- template: Boolean:
			//			If true, ignores ContentPane's stopParser flag and parses contents inside of
			//			a ContentPane inside of a template.   This allows dojoAttachPoint on widgets/nodes
			//			nested inside the ContentPane to work.
			//		- inherited: Object:
			//			Hash possibly containing dir and lang settings to be applied to
			//			parsed widgets, unless there's another setting on a sub-node that overrides
			//		- scope: String:
			//			Root for attribute names to search for.   If scopeName is dojo,
			//			will search for data-dojo-type (or dojoType).   For backwards compatibility
			//			reasons defaults to dojo._scopeName (which is "dojo" except when
			//			multi-version support is used, when it will be something like dojo16, dojo20, etc.)
			//		- propsThis: Object:
			//			If specified, "this" referenced from data-dojo-props will refer to propsThis.
			//			Intended for use from the widgets-in-template feature of `dijit._WidgetsInTemplateMixin`
			//		- contextRequire: Function:
			//			If specified, this require is utilised for looking resolving modules instead of the
			//			`dojo/parser` context `require()`.  Intended for use from the widgets-in-template feature of
			//			`dijit._WidgetsInTemplateMixin`.
			// returns: Mixed
			//		Returns a blended object that is an array of the instantiated objects, but also can include
			//		a promise that is resolved with the instantiated objects.  This is done for backwards
			//		compatibility.  If the parser auto-requires modules, it will always behave in a promise
			//		fashion and `parser.parse().then(function(instances){...})` should be used.
