The kernel doesn't use any directional features. However, it does have a large set of tests, some of which cover math mode: nny change to the \showoutput result will show up. To date, pdfTeX and XeTeX have given identical output for the same (7-bit) input if specials have not been involved (LuaTeX does not as it uses Omega-like directional data). Having TeX-XeT active changes this. As David has already said, we will find a way to work with this, probably duplicating the test file output for pdfTeX/XeTeX but perhaps normalising (if I can think of a way to do it!). -- Joseph Wright -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
