Maybe I still did not fully understand the concepts. Are 'DocumentClass' and 'LayoutFile' two completely distinct concepts such that we never can exchange a 'DocumentClass' for a 'LayoutFile' (but that happen to share a common implementation via some 'TextClass' base right now) _or_ do we have the case that we basically have a concept 'TextClass' coming in two varieties?
