Delete[=All]

    Indicates that the ACEs specified with the Acl qualifier are
    to be deleted. If no ACEs are specified with the Acl qualifier,
    the entire ACL is deleted. If you specify an ACE that was not
    specified with the Acl qualifier, you are notified that the ACE
    does not exist, and the delete operation continues.

    You cannot use this qualifier with the Edit qualifier.
