I don't doubt that there are some, but are you aware of any
specific examples?

I think one reason why existing content models exclude them is
the problem of how to render them. If you have, for example,
numbered footnotes, then how do you number a footnote to a
footnote? And how would an application programatically determine
how to number it? If you have marginalia that annotate other
marginalia, where do you place the additional marginalia?
