Not sure if it is an issue as it seems that you want to use all the
@documentlanguage that appeared, but it should be taken into account
that @documentlanguage can appear more than once in the document.  I am
not sure how having some index entries appear in a @documentlanguage or
another can be taken into account, as when the time comes to sort, I
can't imagine how collating could take into account more than one locale
language.

It could maybe be good to use the same convention about which
documentlanguage to use both in texindex and in the equivalent texi2any
code (yet to be done).
