		//	|	// get the current value of the "foo" property on a node

		//		When passing functions as values, note that they will not be
		//		directly assigned to slots on the node, but rather the default
		//		behavior will be removed and the new behavior will be added
		//		using `dojo.connect()`, meaning that event handler properties
		//		will be normalized and that some caveats with regards to
		//		non-standard behaviors for onsubmit apply. Namely that you
		//		should cancel form submission using `dojo.stopEvent()` on the
		//		passed event object instead of returning a boolean value from
		//		the handler itself.
		// node: DOMNode|String
		//		id or reference to the element to set the property on
		// name: String|Object
		//		the name of the property to set, or a hash object to set
		//		multiple properties at once.
		// value: String?
		//		The value to set for the property
		// returns:
		//		the DOM node
		//
		// example:
		//	|	// use prop() to set the tab index
		//	|	dojo.setProp("nodeId", "tabIndex", 3);
		//	|
		//
		// example:
		//	Set multiple values at once, including event handlers:
		//	|	dojo.setProp("formId", {
		//	|		"foo": "bar",
		//	|		"tabIndex": -1,
		//	|		"method": "POST",
		//	|		"onsubmit": function(e){
		//	|			// stop submitting the form. Note that the IE behavior
		//	|			// of returning true or false will have no effect here
		//	|			// since our handler is connect()ed to the built-in
		//	|			// onsubmit behavior and so we need to use
		//	|			// dojo.stopEvent() to ensure that the submission
		//	|			// doesn't proceed.
		//	|			dojo.stopEvent(e);
		//	|
		//	|			// submit the form with Ajax
		//	|			dojo.xhrPost({ form: "formId" });
		//	|		}
		//	|	});
		//
		// example:
		//	Style is s special case: Only set with an object hash of styles
		//	|	dojo.setProp("someNode",{
		//	|		id:"bar",
		//	|		style:{
		//	|			width:"200px", height:"100px", color:"#000"
		//	|		}
		//	|	});
		//
		// example:
		//	Again, only set style as an object hash of styles:
		//	|	var obj = { color:"#fff", backgroundColor:"#000" };
		//	|	dojo.setProp("someNode", "style", obj);
		//	|
		//	|	// though shorter to use `dojo.style()` in this case:
		//	|	dojo.style("someNode", obj);
