right.  :-) here are the relevant parts from my grammar..
(i think i was using the term "length" for "measure" below..)
---

measure returns [Measure value]
 : INT Unit
 {
   $value = new Measure(Integer.parseInt($INT.text), $Unit.text);
 }
 ;
Unit : 'pt' | 'px' | 'em' | 'ex' ;
INT    :    ('0'..'9')+ ;

WS : (' '|'\t'|'\n'|'\r'|'\f')+ { $channel=HIDDEN; } ;
