Chris Wilson can chime in here, but I thought the idea was to make "inputs" and
"outputs" be attributes instead of methods?

+
+    attribute EventListener onconnect;
+    attribute EventListener ondisconnect;
+
+    // EventTarget interface
+    void addEventListener(DOMString type,
+                          EventListener listener,
+                          optional boolean useCapture);
+    void removeEventListener(DOMString type,
+                             EventListener listener,
+                             optional boolean useCapture);
+    [RaisesException] boolean dispatchEvent(Event event);
+};
