 * @REVISIT: There seems to be quite a bit of code duplication in this class
 *           with LoadXMLAction, loading things, especially with the
 *           validation stuff.  Anyway we could cut that down?  Have one call
 *           the other?  Too close to release to do sucha refactoring but
 *           in 1.4 we should. -CH
