|(musical division) – Contains a subdivision of the body of a musical text.|
The mdiv element may contain one or both of 2 possible views of the music. The score view is the traditional full and open score while the parts view contains each performer's view of the score; that is, his part. These 2 views are necessary because it is not always possible or desirable to generate one from the other. The score and parts elements are placed here and not directly within the body element because score and part characteristics may change from mdiv to mdiv. For example, the 2nd movement of a symphony may require different performing forces (and therefore different score and part layout) than the other movements. The mdiv element may be recursively nested in order to represent music which exhibits this kind of structure. For example, an opera is normally divided into acts, which are in turn divided into scenes.
