Fundamentally DVI describes isolated graphemes on paper. No sequence is
implied, no relation between glyphs, most certainly not directional.
Not even spaces are discernible, nor is it possible to rejoin hyphenated
words and/or line breaks or even do cut&paste except by heuristics.
So I don't think that the DVI format does not make for a sensible
starting point for embedding such information.
