We have explained this many times in the past but it is to do with the
performance gains achieved by not associating text with tokens unless
you really need it and so do so yourself.
You can also do this:
T1 : '/*' r=FRAGRULE '*/' { setText($r.text); } ;
So in practice it is only a minor inconvenience, for a simpler and
faster lexer :-)
