Multiple layouts
In this image, you see three different representations of the same underlying SATB music — one with four separate staves, one with two staves (using multiple voices) and one with two staves (using notes combined into chords).
This can be encoded entirely within a single MNX document. The underlying music (the notes, barlines, etc.) is encoded only once, within the "global" and "part" objects. But there are three separate score objects — one for each visual representation of the music.
A score references a particular layout. The layout object is where the style information is contained: which parts, in which order.
