2.23.81 new D.S. code

[Paul Scott]

I'm, trying to learn the new segno repeat structure.

1. Why do I get a second staff?

2. What does \volta #'() do?

TIA for any help.

Paul


\version "2.23.81"

timing = {
  \set Score.dalSegnoTextFormatter = #format-dal-segno-text-brief
  s1
  \repeat segno 2 {
    s1
    \alternative {
      \volta 1 {
	s1 
      }
      \volta 2 \volta #'() {
        \section
        \sectionLabel "Coda"
      }
    }
  }
  s1
  \fine
}

music = \fixed c' {
  c1 d e f   
}

\score { << \timing \music >> }
