Check the documentation further, or check for an example with a custom
token or custom AST. With ANTLR 2 you used to be able to create your
own Token type and store whatever information you needed in there.
There was some particular method called to actually create the token,
which you could override. That token is passed to the AST constructor
so that the AST could get whatever it needed out of the token. There
must be a similar strategy at play in ANTLR 3.
