+/** Wrapper base class for UNO services which emulates the upcoming
+    mode of automatic runtime Java classes to get rid of the need for
+    queryInterface.
+
+    Because it's not worth the effort to create a runtime generated wrapper
+    for this purpose, as it might be for OOo 2.0, you still have to use
+    UnoRuntime.queryInterface() for interfaces which are optional or come
+    from a subclass.  But for non optional interfaces you can already
+    directly call their methods.
+
+    This wrapper will only work for UNO objects via a bridge, not for
+    direct Java objects.
+
+    @since OOo 2.0.0
