To turn a non-fragment lexer rule into a fragment rule, you just 
put the word "fragment" in front of it.  This means that it's no 
longer considered a possible candidate to be selected as a full 
token -- it has to be referenced from other lexer rules in order 
to have any effect.  (It is still allocated a token id, though, 
which is useful for more advanced problems.)

Have a look at the example v3 grammars.  You might also want to 
get TDAR (the ANTLR book).
