 /**
- *
+ * This implementation of {@link ResourceBundle.Control} is intended to be used for showing 
+ * RelationAttribute values (data base driven enum} values in Bebop Controls using 
+ * {@link GlobalizedMessage}. Used it by creating a {@link GlobalizedMessage} like this:
+ * 
+ * <pre>
+ * new GlobalizedMessage("attribute_key",
+                         "attribute_name",
+                         new RelationAttributeResourceBundleControl());
+ * </pre>
+ * 
+ * Replace <code>attribute_key</code> with the key of the attribute value and 
+ * <code>attribute_name</code> with the name of the relation attribute. 
+ * 
+ * To see this action, please refer for example to {@link GenericOrganizationalUnitPersonAddForm}.
+ *
