Antenna House put a great deal of effort into implementing Thai glyph 
composition--it is nontrivial. It is probably not reasonable to expect 
XEP to do Thai glyph composition unless they go to the same level of effort.

Of modern languages, Thai is probably one of the worst cases when it 
comes to glyph composition because of the number of elements involved in 
each glyph and the grammar-sensitive rules on composition. I don't 
pretend to understand them except to understand that they are complex.

Cheers,

Eliot
