(<turn> may not have child elements)
Remarks

See Read, p. 246-247. Whether the turn is accented or unaccented may be inferred from the timestamp — accented turns occur directly on the affected beat, unaccented ones do not.

Constraints

Must have one of the attributes: startid, tstamp, tstamp.ges or tstamp.real.
