No, top-level \paper sets a default for the \book level \paper.
top-level \layout sets a default for \score level \layout.
\layout { X }
\paper { Y }
mean
$defaultlayout = \layout { \$defaultlayout X }
$defaultpaper = \layout { \$defaultpaper X }
independenty of this
\book {
\score {
\layout {
%% A
}
}
\paper {
%% B
}
}
means
\book {
\score {
\layout { \$defaultlayout
%% A
}
}
\paper { \$defaultpaper
%% B
}
}
If at run time, a score-level layout variable,
such as ragged-right, is looked up in %A.
If it's not found, it is looked
up in %B. If it's not found in %B, then it is
assumed undefined.
iow. There are 2 orthogonal mechanisms:
- toplevel output-defs set defaults, which are
copied implicitly during parsing ( $defaultlayout / $defaultpaper )
- the \paper (book level) is parent to \layout (score level),
this parent relation is employed during formatting.
