The whole discussion is 1-2 storeys above my pay grade, so sorry for piping up. I just want to second the doubts whether it's really a good idea to use the term "item" here, which has a very specific and well-defined meaning in LilyPond lore. Apart from this, your list seems very convincing to me. Lukas
