Hello Raphael, couldn't resist answering your question. I am a married man, and
I sure look forward to have a 1:1 relation between clearly differentiated
"objects" (i.e. persons) :)

But why do you want a 1:1 at all? Surely if two objects are 1:1 then they are
two parts of the same object -- unless one part is optional.
