I think I get the idea of what you're saying here... Setting an index in 
typeSpec intuitively seems the most elegant way to go to me, but is there 
documentation available on how to accomplish this? I mean, I guess it's 
needed to add an attribute to typeSpec's class definition, which is probably 
built-in to antlr?

Thanks,

Hans
