This is interesting. If we can produce (good enough) tagged PDF, we
can from this also produce (good enough) HTML, XML and Word documents.
And I believe that from (good enough) XML we ought to be able to
produce (good enough) tagged PDF.

So we are, in part, also talking about round-tripping typesetting, and
LaTeX to XML.
