OK, that's an example I can run. But I don't see what the issue is
that that solves. Isn't that just a conventional repeat without
an opening : (quite usual) and without a closing :| (less so).

It would be nice to see a screenshot of "this kind" of music.
I'm not sure the example that I posted is at all appropriate.

Thanks everyone. I tweaked my definition to use

\allowVoltaHook "|"

altBracket = #(define-music-function (parser location tag) (string?)

#{ 

    \once \override Score.VoltaBracket.shorten-pair = #'(0.3 . 0.3)

    \set Score.repeatCommands = #(list (list 'volta (markup #:number tag))) 

#})

which gives me precisely what I want. Here is an example using both \repeat ... \alternative endings and \altBracket alternatives.
