Hi Luc,

I don't know if I want to be rollled..... ;-)

I think that is a reasonable approach But you did specify a new type:  
"provenance container" and a new role: "asserter"

I think these are new "concepts" but maybe you want to call them 
something else. Maybe we are getting into the discussion of how to 
extend the model....

Thanks,
Paul
