For musikalische Würfelspiele, each measure could be encoded in a separate
Below is an encoding of the above score, using <expansion plist="#label-B #label-C #label-A" xml:id="expansion-L3F1" />to indicate the performance sequence of measure 2, 3, then 1. <?xml version="1.0" encoding="UTF-8"?>

</mei>But for this sort of algorithmic score, it would be better to use XSLT to render the performance sequence score by rearranging/selecting measures in the original score. See related: https://dice.humdrum.org and https://verovio.humdrum.org/?file=dice/mozart/k516f.krn Here is a particular realization: Where the sequence of measure numbers is given in the URL: |

Some ossia- or choice-like element would be useful to encode non-fixed or optional contents like aleatoric pieces ("musikalische Würfelspiele" etc.).
The options in this case are given by the composer, but the choice is to be made by the performer during or prior to the performance (thus it is not an editorial decision, so editorial elements like and will not do).
Something like ossia at a higher level than 1 measure/1 staff?
