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