I'm not a percussionist; but it would seem reasonable for "sn \rest" to 
work the same as "fis \rest".

I take it parser.yy would need updating to something like this:

////
simple_element:
  DRUM_PITCH optional_notemode_duration optional_rest {
    Music *n = 0;
    if (scm_is_true ($3))
      n = MY_MAKE_MUSIC ("RestEvent", @$);
    else
      n = MY_MAKE_MUSIC ("NoteEvent", @$);
    set_property (n, "duration", $2);
    set_property (n, "drum-type", $1);

    $$ = n->unprotect ();
  }
