aha, yes, the typical answer should have been: "we cannot help you unless you provide ..."

-- what the intention is. Should the "double bar" correspond to a certain operation "in its own right", or does each bar correspond to an operation that is applied twice at this occasion?

(... such as the closure of the closure ... in which case I would consider \bar very wrong.)

So, Rodolfo: no, NOT solved yet :-)

Cheers, 

    Uwe.
