    The right to change file characteristics, including the
    protection code and ACL.

    Special restrictions apply to changing the owner of a file.
    Usually, you need privileges. However, if a file is owned by
    a general identifier, you can change the file owner under the
    following conditions:

    o  You have control access to the file.

    o  You hold the identifier currently owning the file and the
       identifier intended to own the file, and both identifiers have
       the Resource attribute.
