What would be nice is to have a way to semantically indicate precisely 
when and how many times an alternative is used.

Consider a case when you have a first ending that would be labelled 
"1.3." and a second ending that is labelled "2.4.5.".  Currently, this 
can be done using custom repeat commands but \unfoldRepeats does not 
know how to parse the volta text and produce the right expansion.

Perhaps:

%%%%
\repeat volta 5 {
  ...
}
\alternative 1,3 {
  ...
}
\alternative 2,4,5 {
  ...
}
%%%%
