I must be explaining myself poorly. My apologies. Elements in the  
EG_ColorTransform group can must occur once and once only. So neither  
(a|b)* nor (a?,b?)* is relevant, because they can produce arbitrary  
combinations such as ababbba.

What is relevant is the order (lumMod, lumOff) and not (lumOff, lumMod).  
Or am I misinterpreting the group?
