Nope, I tried "Krishna Tamil/GR:classical=true;pullishape=ring" (the
name of the second feature was actually pullishape, and are these
things case-sensitive?). However there is still no effect.

Would appreciate it if you could look into the feature thing when you can.

Heh probably -- but see my later posts. Seems there's no intrinsic bug
with SMP/XeTeX/Graphite, but something going wrong in reading the font
tables or such. When there are OT tables, Gr renders right!

That's right. Right now (with the font with Gr+OT tables) If I use it
without /GR there is no rendering but if I use /GR there is correct

Thanks for your continued support, you people are great! :-)
