case sensitive affiliated roles

[Eloitor]

The documentation uses ExecutiveProducer and executive-producer and says that it is case insensitive. Does this case insensitivity include - ?

Also this example works:

Example cite @example

#let bib = bytes("
example:
    type: Book
    title: Interesting book
    author: Surname, Name
    date: 2025
    affiliated:
      - role: translator
        names: Else, Someone
")

#bibliography(bib, style: "springer-humanities-author-date")

but it doesn't work if I replace translator by Translator
