We will definitely provide a drl5.5 translator. I'm reluctant to do a 
5.5 executable parser, because we'll have to maintain it indefinitely; 
and all the cost that is involved with this. And also restructuring of 
all our test frameworks to ensure both 5.5 and 6.0 continue to be tested.

I'm not say that we won't do a 5.5 executable parser, when the time 
comes it's open for debate. I'm just very apprehensive about it. Let's 
leave this discussion until the time is relevant, we can start a new 
thread on it then.

Either way I'd definitely encourage your work (and others if they want 
to do their own language) as independant language efforts.
