-/**\r
- * The Spring Extension Factory builds a bridge between the Eclipse Extension\r
- * Registry and the Spring Framework (especially Spring Dynamic Modules).\r
- * \r
- * It allows you to define your extension as a spring bean within the spring\r
- * application context of your bundle. If you would like to use this bean as an\r
- * instance of an extension (an Eclipse RCP view, for example) you define the\r
- * extension with this spring extension factory as the class to be created.\r
- * \r
- * To let the spring extension factory pick the right bean from your application\r
- * context you need to set the bean id to the same value as the id of the view\r
- * within the view definition, for example. This is important if your extension\r
- * definition contains more than one element, where each element has its own id.\r
- * \r
- * If the extension definition elements themselves have no id attribute the\r
- * spring extension factory uses the id of the extension itself to identify the\r
- * bean.\r
