well don't forget, there has been some relatively successful attempts to 
do this in the past [1] [2].. which seems to be very close to being 
adopted into mainline haxe development tree, so I would favour following 
this approach. Whatever you do decide to cook up, it should be usable 
independently of sandy too - if there are performance gains over the 
haxe API, and you are using compiler switches, sandy could get an 
additional compile file for the 'fast' xml version.
