        If CAPCO rules do not apply to the document then the rule does not apply
        and we return true. If it is a CAPCO resource then we check that if we have
        an element having attribute disseminationControls without a value of 
        [FOUO] then we return true because the rule does not apply. Otherwise
        we make sure the attribute classification is specified with a value of [U] 
        on the same element.
