      <miscellaneous-field name="description">The number of staff lines can be
      modified by using the staff-lines child of the staff-details attribute.
      This can happen globally (the first staff has one line globally) or
      during the part at the beginning of a measure and even inside a measure
      (the second part has 5 lines initially, 4 at the beginning of the
      second measure, and 3 starting in the middle of the third
      measure).</miscellaneous-field>
