Oh, and language support in OpenType seems pretty well considered,  
although I guess there's no reason why that couldn't be done in AAT  
via another plain old feature. I've yet to see a font that makes  
punctuation space via French rules, although I've never really looked...

While AAT's feature-naming as whatever you like is nice for GUI apps,  
for fontspec it's kind of harder to support :)
