+    1. It reads the
+    org.openoffice.Office.Impress/MultiPaneGUI/Framework/ResourceFactories
+    configuration data that maps from resource URLs to service names of
+    factories that can create resources for the URLs.  When the
+    configuration controller wants to create a resource for which it does
+    not have a factory, it asks the ModuleController to provide one.  The
+    ModuleController looks up the service name registered for the URL of the
+    resource and instantiates this service.  The service is expected to
+    register on its creation a factory for the resource in question.
+
+    2. The ModuleController reads on its creation
+    org.openoffice.Office.Impress/MultiPaneGUI/Framework/StartupServices
+    configuration data and instantiates all listed services.  These services
+    can then register as listeners at the ConfigurationController or do
+    whatever they like.
