Ok, I have thought a bit more about this. The problem with
"\setNoteLanguage" which supposedly holds until the "end of a group"
(whatever that may be) is that it still commingles execution and syntax.
Since note names are basically syntactic entities, being able to change
the syntax on the fly is just asking for trouble. In particular if you
want to generate or interpret stuff.
I should think it saner to have the language be part of the syntax.
Namely some form of \withNoteLanguage rather than \setNoteLanguage. And
I think it would be saner if included files would by default be in
Netherlands, unless they are explicitly included using possibly
something like
\withNoteLanguage "deutsch" \include
(which is not likely a good idea to support at all). That way stuff has
more of a chance to be reusable. It would also mean that if somebody
wrote some parts in the input language he preferred, it would still
seamlessly fit into projects from others.
