This type, which implements the IEnumerator interface, is returned by the GetEnumerator( ) methods of XmlSchemaObjectCollection and XmlSchemaObjectTable and provides a mechanism to iterate over their elements. The MoveNext( ) method moves the enumerator to the next element, and the Current property returns the instance of XmlSchemaObject at the enumerator's current location.
