   6 example really contains three drum staves, but as it progresses, empty ones
   7 are removed: this example has three staves, but some of them
   8 disappear: note how the 2nd line only has the bar number 2. (That the
   9 bar number is printed might be considered a bug, however, the scenario
  10 of all staves disappearing does not happen in practice.)

  12 Any staff brackets and braces are removed, both in the single staff
  13 and no staff case.
