Thanks for the reply. I'm still a little confused.
Here's a little tree grammar snippet, for which I'll
charge nothing ;)

schema : type+
             ;

type	:	TYPE ID 
		{
		Type t = types.get($ID.text);
		String className = t.getClassName();
		ArrayList<String> k = t.getKeys();
		ArrayList<String> a = t.getAttributes();
		}
		->
template(name={className},attributes={a},keys={k})
		<<
		public class <name> {
                   blah blah blah
		}
		>>
	;

If I have n types in my model I'll wind up with n
concatenated class definitions in the StringTemplate
output. 

I suppose I could instantiate a template in the
grammar action and do away with the -> clause.
