In 1998 I concluded that such a thing is impossible if it is to include all
documents that run "correctly" -- hard to define, e.g. think about $f(x$)
-- through latex the program (which now is one of pdflatex, xetex, or
lualatex -- maybe also the various guises of tex4ht and latexml).

It is possible, however, if one restricts to documents under a LaTeX
profile, as I explained at TUG 2010 in my talk "LaTeX Profiles as Objects
in the Category of Markup Languages
<https://www.albany.edu/~hammond/presentations/Tug2010/>".
