       * This allows you to answer the question: For this workItem, what changed?
       * Auditors have been known to love this... :)
       * SCMs known to implement this are:
       * <ul>
       * <li>IBM Rational Team Concert (workItem)

       * <li>IBM Rational ClearQuest Enabled UCM ClearCase (task)

       * There may be others that support this feature.
       * <P>

       * information (by way of a workItem/task) is supplied.

       * need to be set, as the need for a workItem may be optional.
