The number of possible sizes would be unlimited since it can be defined for
every staff individually (in staffDef element) if necessary. Our proposal
was nonetheless to have a cue-size for the most common cases where we have
only one size of cue-size staves and to have it defined at a higher level
(in scoreDef element).
