I am working on a document that contains index items both in the text and in the footnotes. The footnote items are shown differently than the text items. To implement this, I followed this answer and I will use the same mwe to illustrate my page numbers order problem. My desired result is:
index, 1, 1n1, 2n2, 3, 3n3, 5ff.
I have tried two ways:
1.
For index I have defined a markup-range (f., ff.) and it works fine. The problem is the location class order; the location classes follow each other, means, first all item page numbers from the text (\index) and then all from the footnotes (\indexfn). Is there a possibility to build a "mixed" location class order?

(define-location-class "pagefn" :var
("arabic-numbers" :sep " " "arabic-numbers"))
(define-location-class-order ("arabic-page-numbers" "pagefn"))
;; End
If I add "-M ff-ranges" I get a correct order but without f., ff. (I believe for the same reason as described below)
2.
I only use \indexfn everywhere, which is possible, because it recognizes whether it is in the footnote or not. The order is correct. The problem here is that I don't know how to define a markup-range for var-location-class. The documentation says:
... building of ranges is currently only allowed for standard classes
:varand:min-range-lengthmust not be used together.
Is there another possibility that I don't see?
