What should it be?
The presence of a \layout block in a score makes for typeset output. \paper contains things like paper dimensions only necessary for typeset output. Also base file names that are also relevant for MIDI. Global markup currently only gets to see the \paper block. That also concerns things like \score markup that can get information for typesetting from \layout blocks. Layout blocks "inherit" from the paper block: when a variable in a layout block is not set, it is taken from the respective paper block. Currently a "paper-book" where the typesetting is done only stores the relevant paper block. Consequently, any page-level/top-level markup currently gets only the paper block as its "layout" parameter. That is not accepted as layout block in a score markup. Suggestions? -- David Kastrup
