The rhythmic meaning of the components of a ligature is typically contextual, not absolute; therefore, an interpretative duration may be encoded on each of the components using either the dur.ges attribute or the num and numbase attribute pair. The ligature element should not be used for brackets in modern notation that indicate notes that were part of a ligature in the original source.
