@staff(optional)Signifies the staff on which a notated event occurs or to which a control event applies. Mandatory when applicable. One or more values of datatype positiveInteger, separated by spaces. att.staffident
@startid(optional)Holds a reference to the first element in a sequence of events to which the feature applies. Value conforms to data.URI. att.startid
@subtype(optional)Provide any sub-classification for the element, additional to that given by its type attribute. Value of datatype NMTOKEN. att.typed
@synch(optional)Points to elements that are synchronous with the current element. One or more values from data.URI, separated by spaces. att.common.anl
@to(optional)Records a timestamp adjustment of a feature's programmatically-determined location in terms of musical time; that is, beats. Value conforms to data.TSTAMPOFFSET. att.visualoffset.to
@tstamp(optional)Encodes the onset time in terms of musical time, i.e., beats[.fractional_beat_part]. Value conforms to data.BEAT. att.timestamp.musical
@tstamp.ges(optional)Captures performed onset time in several forms; that is, ppq (MIDI clicks and MusicXML 'divisions'), Humdrum **recip values, beats, seconds, or mensural duration values. Value conforms to data.DURATION.gestural. att.timestamp.performed
@tstamp.real(optional)Used to record the onset time in terms of ISO time. Value conforms to data.ISOTIME. att.timestamp.performed
@type(optional)Characterizes the element in some sense, using any convenient classification scheme or typology. Value of datatype NMTOKEN. att.typed
@vo(optional)Records the vertical adjustment of a feature's programmatically-determined location in terms of staff interline distance; that is, in units of 1/2 the distance between adjacent staff lines. Value conforms to data.MEASUREMENTREL. att.visualoffset.vo
@when(optional)Indicates the point of occurrence of this feature along a time line. Its value must be the ID of a when element elsewhere in the document. Value conforms to data.URI. att.alignment
@x(optional)Encodes an x coordinate for a feature in an output coordinate system. When it is necessary to record the placement of a feature in a facsimile image, use the facs attribute. Value of datatype decimal. att.xy
@xml:base(optional)Provides a base URI reference with which applications can resolve relative URI references into absolute URI references. Value conforms to data.URI. att.commonPart
@xml:id(optional)Regularizes the naming of an element and thus facilitates building links between it and other resources. Each id attribute within a document must have a unique value. Value of datatype ID. att.id
@y(optional)Encodes an y coordinate for a feature in an output coordinate system. When it is necessary to record the placement of a feature in a facsimile image, use the facs attribute. Value of datatype decimal. att.xy

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.

Constraint

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