Hello Khaled,
That suggests that TeX--XeT is not providing the tools required to do a
decent job in XeTeX: is that a fair reading? (I'd guess that there were
reasons for the Omega/Aleph/LuaTeX move from TeX--XeT to other
approaches, but as a non-expert was not sure how to read it.)
A slightly wider question which this leads me to: do I take it that
getting some (minor) additions to XeTeX might be possible? There was
some discussion last week about a few pdfTeX primitives that might be
useful.
