+		//	method: String?
+		//		The HTTP method to use. "GET" or "POST" are the only supported
+		//		values.  It will try to read the value from the form node's
+		//		method, then try this argument. If neither one exists, then it
+		//		defaults to POST.
+		//	handleAs: String?
+		//		Specifies what format the result data should be given to the
+		//		load/handle callback. Valid values are: text, html, xml, json,
+		//		javascript. IMPORTANT: For all values EXCEPT html and xml, The
+		//		server response should be an HTML file with a textarea element.
+		//		The response data should be inside the textarea element. Using an
+		//		HTML document the only reliable, cross-browser way this
+		//		transport can know when the response has loaded. For the html
+		//		handleAs value, just return a normal HTML document.  NOTE: xml
+		//		is now supported with this transport (as of 1.1+); a known issue
+		//		is if the XML document in question is malformed, Internet Explorer
+		//		will throw an uncatchable error.
+		//	content: Object?
+		//		If "form" is one of the other args properties, then the content
+		//		object properties become hidden form form elements. For
+		//		instance, a content object of {name1 : "value1"} is converted
+		//		to a hidden form element with a name of "name1" and a value of
+		//		"value1". If there is not a "form" property, then the content
+		//		object is converted into a name=value&name=value string, by
+		//		using dojo.objectToQuery().
