Anyway i finally have to say that it is a pity that, instead of (making the engine as such multi-pass and) instrumenting the macros for different output formats that need meta-information, and extending the macros sets to include more meta-information that may be usable in output devices, so many other languages and text formats have been invented where no person at all only spends a single thought on using the necessary commands to provide this meta-information as part of the format.
