  Oops! My fault for not RTFM entirely, I usually read directly the syntax 
reference. The section on the syntax chapter seems to induce to think that 
only one instance is permited. At least that layering-blending capability 
is not mentioned at all... but thast's the nice thing about POV, it can do 
so many things that you are always learning. Great! 

  But now, I'm curious about how it looks...  another thing for my "pending 
tests" list! :(
