1    /BRANCH

    Format options:

       /BRANCH=branchname
       /NOBRANCH (default)

    Specifies whether CDO creates a version on a new branch line or
    on an existing line of descent. The BRANCH option you specify in
    the REPLACE command overrides any BRANCH option you specified in
    the RESERVE command.

2    /CLOSURE

    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.

3    /LOG

    Format options:

       /LOG
       /NOLOG (default)

    Specifies whether CDO displays text identifying each element as
    the element is replaced.
