I might get around to trying to devise a solution myself, but there's  
no knowing when I may have the time and interest to tackle that. But  
if there's a clearly-specified request that seems to fit into the  
general design of XeTeX, and even more so if an actual patch is  
offered, the chances of something getting done are dramatically  
increased (as happened recently with several primitives the LaTeX3  
team wanted, for example).

Oh, I guess that was code from TeX-e-Parsi, not Omega. My mistake --  
but the point remains: as you may have noticed, I can't simply copy  
that code into xetex, and I can't (and probably won't even try to)  
figure out how to incorporate it if I don't know exactly what it is  
supposed to do.

How would that resolve the problem of color, for example? If the  
document contains, in effect,

    preceding text \special{color push rgb 1 0 0} red and more red  
\special{color pop} following text

how exactly would \beginspecial and \endspecial be used, and what is  
their effect? I don't think I understand yet, sorry.
