	//		The WikipediaStore is a data store interface to Wikipedia, using the
	//		Wikipedia SMD spec from dojox.rpc. It currently is useful only for
	//		finding articles that contain some particular text or grabbing single
	//		articles by full name; no wildcards or other filtering are supported.
	//	example:
	//		|	var store = new dojox.data.WikipediaStore();
	//		|	store.fetch({
	//		|		query: {title:"Dojo Toolkit"},
	//		|		onItem: function(item){
	//		|			dojo.byId("somediv").innerHTML = item.text["*"];
	//		|		}

		//		|	store.fetch({
		//		|		query: {title:"Dojo Toolkit"},
		//		|		// define your handlers here
		//		|	});

		//		|			text: "dojo"
		//		|		},
