IIRC, XeTeXHanLayoutEngine adds support for user-specified features; the 
original ICU engines didn't offer this API, but *only* apply the default 
features they consider appropriate for the script.

It might be reasonably simple to create a XeTeXHangulLayoutEngine based 
on the ICU one, with a similar extension for user features. But I 
haven't looked closely...
