Format options:

       /CLOSURE=keyword
       /NOCLOSURE (default)

    Specifies whether CDO replaces additional elements. A CLOSURE
    operation fails if any element is a child of an element outside
    the area defined by the CLOSURE keyword.

    The /CLOSURE qualifier takes one of the following keywords:

    CLOSURE
    Keyword      Behavior

    TO_BOTH      Replaces the element specified and all parents and
                 children.

    TO_BOTTOM    Replaces the element specified and all children.

    TO_TOP       Replaces the element specified and all parents.

    If you specify TO_BOTH or TO_TOP, CDO ignores parents of the top
    collection.
