It shouldn't be too hard to patch doc2html to do look at argument no. 2,
the mime type.

I've heard nothing about it other than knowing of it's existance. Back when
the redhat-announce mailing list was still active, someone posted a message
announcing the availability of this program in RPM form. I made a mental
note to look into it someday, but haven't done so yet.
Would a .csv be plain, indexable ASCII text? If so, that should do the
trick too. You still have the problem of differentiating between word
and excel documents in your script in either case.
