+ 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.
