The <beam> sub-element is allowed so that custom beaming may be indicated, e.g., a septuplet may be divided into a group of three plus a group of four notes. See Read, p. 187-215. The <tuplet> element may also used for bowed tremolo (Read, p. 394) and double, triple, or flutter tonguing (Read, p. 348-349); that is, for repetition of the same pitch. In the case of irrational durations, such as such as two quarter notes in the time of five 8th notes in a measure of 5/8 time, decimal values may be used in the @dur.ges attribute. For example, the @dur.ges attribute would take the value 2.5 if the @midi.div attribute’s value was 1. The @num and @numbase attributes may be used for explicit labelling of a tuplet, such as, '3' with an 8th-note triplet, '3:2' over a quarter-note triplet, etc. The rendering of the ratio, however, is dependent on the @num.format attribute found in the att.vis.tuplet attribute class.
