   /* Get both the immediate container and the root container */
   nRet = L_AnnGetContainer(hAnnObject, &ThisContainer);
   if(nRet != SUCCESS)
      return nRet;
   nRet = L_AnnGetTopContainer(hAnnObject, &TopContainer);
   if(nRet != SUCCESS)
      return nRet;
   /* Compare the container handles */
