Perhaps you're right about that. I don't know much about this stuff. We
already provide metadata in the form of local-variable declarations in
comments, but I recognize that this should also be applicable to files that
aren't necessarily code and don't necessarily have a comment syntax.
(Besides, trying to record this stuff in comments would likely be a
nightmare, if not also problematic.)

That sounds reasonable to me, from the little I know of this. As I mentioned
to Thi, this is not something that I expect to work on, so I'll generally
bow out of trying to design and implement this. I was really just trying to
find out if something already existed, or was planned, which I might be able
to take advantage of for my highlighting code.
