   David, don't you think that this is an implementation detail of the
   software responsible to interpret a fresnel stylesheet? If not, how can
   we model that without entering the 'behavioral' space?

well, it is an implementation detail of how the responsible software
operates, but I think it will be good to keep in mind that it might
be worth crafting lenses that spit out far more data than one could
reaosnably imagine viewing all at once in a rendering.
