Not really a practical or understandable one. But you may have a look at
https://github.com/openlilylib/scholarly/blob/master/annotate/engraver.ily#L86

Here an annotation will get a property for the context (i.e. to print
the context where the annotation refers to). If the context is given
explicitly in the annotation (i.e. there's some \with { context = "flute
1" } or so) this is taken. As the next step the function looks for a
named context (i.e. the music happens to be in something like \new Staff
= "flute 1"), and if that fails too it takes the containing directory
name (which is pretty stupid and only makes sense in the project setup
where the scholarLY package was originally developed).

So the idea is that at some point you can extract the name of the Voice
or Staff the current music is in and use that as a label or a lookup key
for something.
