+/**
+ * The Interface IExtension.
+ * 
+ *	 IExtension defines an extension of the data defined in the UIC standard
+ *
+ *   If not agreed bilaterally otherwise these extensions must be ignored.
+ *
+ *  --    the generic non - standard extension contains:
+ *  --            - an extension id to distinguish different extensions
+ *  --            - the extension data as binary data
+ *  -- proprietary extensions are by definition proprietary. This standard provides
+ *  --           the means to identify these extensions 
+ *  --           within the data and to skip these data.
+ *  --           the evaluation of these data and the unique identification of the extensions 
+ *  --           via the extension id is in the 
+ *  --           responsibility of the railways which use these extensions.
