Remarks

The starting point of the line may be identified in absolute output coordinate terms using the x and y attributes. The attributes in the att.visualOffset class may be used to record horizontal, vertical, or time offsets from these absolute coordinates or from the location of the element reference in the startid attribute. Similarly, the terminal point of the line may be recorded using the x2 and y2 attributes. Attributes in the att.visualOffset2 class maybe used to record the offsets of the ending point. Textual content of the line element, e.g., 'gliss.', may be rendered with the line. The appearance of the line is captured in the color, form and width attributes.

Constraints

When used in the symbolDef context, must have either a startid attribute or x and y attributes.
When used in the symbolDef context, must have either an endid attribute or both x2 and y2 attributes.
When used in the score context, must have a startid, tstamp, tstamp.ges or tstamp.real attribute or both x and y attributes.
When used in the score context, must have an endid, dur, dur.ges, or tstamp2 attribute or both x2 and y2 attributes.
