 *
 * Parameters:
 *  dwAspect        DWORD indicating which aspect has changed.

 *  containers that want to make optimizations for objects that are
 *  not in a saved state, so on this you have to disable such
 *  optimizations.  Generally only the OLE default handler
 *  cares about this.
 *
 * Parameters:
 *  None

 *
 * Parameters:
 *  None
 *

 * Purpose:
 *  Informs the advise sink that a linked compound document object
 *  has changed its link source to the object identified by the
 *  given moniker.  This is generally only of interest to the OLE
 *  default handler's implementation of linked objects.
 *
 * Parameters:
 *  pmk             LPMONIKER specifying the new link source.
 *
 * Return Value:
 *  None
