Hi,

Would it make sense to link papers and headers, by adding a header_ slot to
Output_def or by using a given variable in the output_def scope_ (which would
be set by Paper_book or Paper_score instances), so that
Text_interface::interpret_markup can build the header:* properties itself
before intrepreting the markup?  That way, header:title and co would be
accessible to top-level markups and markups inside music.
