My understanding of WYSIWYG is not really that "the printer version is equal
to the screen version" (after all, TeX gets that: the xdvi rendering is the
same as the printer's).  Instead, the underlying idea is that there is no
"deep representation", or at least that you can at most manipulate
it implicitly.

No: most WYSIWYG word-processors will happily accept (and print) colors in
your document, even when your screen is black&white.  I.e. the way it
typically works is that there *is* a deep representation but it can only be
manipulated implicitly through the superficial representation which is
displayed with "the best possible rendering on the current output device".

I guess I still don't understand the model you're thinking of, which doesn't
involve an explicit deep representation and yet isn't WYSIWYG either.
