Hmm, it seems that my musicxml2ly development is really pushing the edges of lilypond quite frequently.... MusicXML files can have arbitrarily nested (actually overlapping, but that's not supported by lilypond anyway) part groups. See e.g. http://reinhold.kainhofer.com/temp/Musicxml2ly_SampleFiles/collated-files.html In the 08b-StaffGroups-Finale.ly file, the [[Oboe, English Horn], Clarinet] should also be a StaffGroup... From a user's POV, even requiring InnerStaffGroup instead of StaffGroup is not obvious. After all, as a user, I simply want to group together some staves. Why does the depth matter (of course, internally it does, but I'm not taking about internals)? This shows once more that lilypond is rather a programming language, which offers a powerful interface to the deep-level layout machine. You can do a lot, but these things require manual intervention by the user and cannot easily be automated (i.e. created by a program). You realize that when you are working on such a converter....
