That I use XeTeX; I do not use XeLaTeX, ConTeXt or any other
higher-level interface.  I use the raw engine, with Knuth's
plain format, and thus any solution that is predicated on the
use of (e.g.,) "fontspec", "LaTeX", "XeLaTeX", "ConTeXt", and
so on, cannot be of use to me in my quest.

Yes, I have been experimenting with this, but a native
(XeTeX) solution would be preferable ...

That would be useful, were it it not for the dependency
on LaTeX and LaTeX packages.
