startho(optional)Records the horizontal adjustment of a feature’s programmatically-determined start point. Value conforms to data.MEASUREMENTSIGNED.
startid(optional)Holds a reference to the first element in a sequence of events to which the feature applies. Value conforms to data.URI.
startto(optional)Records a timestamp adjustment of a feature’s programmatically-determined start point. Value conforms to data.TSTAMPOFFSET.
startvo(optional)Records a vertical adjustment of a feature’s programmatically-determined start point. Value conforms to data.MEASUREMENTSIGNED.
synch(optional)Points to elements that are synchronous with the current element. One or more values from data.URI, separated by spaces.
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.
tstamp(optional)Encodes the onset time in terms of musical time, i.e., beats[.fractional beat part], as expressed in the written time signature. Value conforms to data.BEAT.
tstamp2(optional)Encodes the ending point of an event, i.e., a count of measures plus a beat location in the ending measure. Value conforms to data.MEASUREBEAT.
type(optional)Designation which characterizes the element in some sense, using any convenient classification scheme or typology that employs single-token labels. One or more values of datatype NMTOKEN, separated by spaces.
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.MEASUREMENTSIGNED.
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 is a decimal number.
x2(optional)Encodes the optional 2nd x coordinate. Value is a decimal number.
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.
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 is a valid xml:id.
y(optional)Encodes a 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 is a decimal number.
y2(optional)Encodes the optional 2nd y coordinate. Value is a decimal number.

Remarks

The lv element captures the graphical, "tie-like" symbol. Any associated text, such as "l.v.", must be captured using a dir element.

Constraints
