@next (optional) Used to point to the next event(s) in a user-defined collection. One or more values from data.URI , separated by spaces. att.common.anl
@num (optional) Along with numbase, describes duration as a ratio. num is the first value in the ratio, while numbase is the second. Value of datatype positiveInteger. att.duration.ratio

Remarks

The proport element is provided for the encoding of mensural notation. It allows the description of note durations as arithmetic ratios. While mensuration refers to the normal relationships between note durations, proportion affects the relations of the note durations to the tactus.
