Description
The backup and forward elements are required to coordinate multiple voices in one part, including music on multiple staves. The backup type is generally used to move between voices and staves. Thus the backup element does not include voice or staff elements. Duration values should always be positive, and should not cross measure boundaries or mid-measure changes in the divisions value.

1..1 |
|
Duration is a positive number specified in division units. This is the intended duration vs. notated duration (for instance, swing eighths vs. even eighths, or differences in dotted notes in Baroque-era music). Differences in duration specific to an interpretation or performance should use the note element's attack and release attributes.
