How about this: (slight variation on a snippet from the LSR:

\score {
 \relative c'
 <<
   \new Staff {
     <<
       \new Voice \with {
         \consists Mark_engraver
         \consists "Staff_collecting_engraver"
       }
       { c4 d e f 
         \mark \default
         c4 d e f 
       }
       \new Voice \with {
         \consists Mark_engraver
         \consists "Staff_collecting_engraver"
       }
       { s4 s s s
         \mark \markup { "Play violently" } 
         s4 s s s 
       }
     >>
   }
 >>
 \layout {
   \context {
     \Score
     \remove "Mark_engraver"
     \remove "Staff_collecting_engraver"
   }
 }
}
