If that's the case, then this might be a bug, because, as far as I can tell, it doesn't work with 3.1b2--unless I'm just using the wrong syntax.

Here's what I've got:

Parse.g:
        parser grammar dsn_hdr;

        options
        {
          tokenVocab=Lex;
        }
       
       /* Parser Rules */


Lex.g:
        lexer grammar Lex;


        /* Lexer Rules */


Of course this all works if I copy the lexer rules to the parser.  Is this the correct syntax?
