[antlr-interest] about lexer

[=?gb2312?q?=CB=EF=BC=CD=B8=D5=20Jigang=20(Robert)=20Sun?=]

To keep lexical grammar tidy, I would like define a rule in several lines, for example,

ID: UpperCase | LowerCase;

UpperCase: 'A'..'Z';
LowerCase: 'a'..'z';

The UpperCase and LowerCase are only used for convenience, there is no such token name used in
parser. But it complains. 

Is any  way to sort it out?

Thanks.

Jigang
