  69      * that can be used as a place holder for the real element or group
  70      * object it is referring to.
  71      * So whenever the parser detects an element or group reference, it creates
  72      * a XsdReference and returns it instead of the XsdElement or XsdModelGroup.
  73      * During a later phase, the resolver will look for all XsdReferences
  74      * in the schema and will replace them with their referring XsdElement or
  75      * XsdModelGroup objects.
