The point about specials is one I

bidi package does not patch \special. It only make changes in packages like color, xcolor and hyperrref, etc. And this makes them work in a very limited case. For example, if you use color package in RTL with bidi package, color works correctly only if your colored text stays on one line.

My advice: do not waste time on TeX--XeT; it's useless. I have spent four years developing bidi package using TeX--XeT and I can tell you that it has many bugs/limitations.
