| * can be retrieved and deleted with the following line of code. |

| * method <CODE>addHeaderElement</CODE> creates a new <CODE> |
| * HeaderElement</CODE> object and adds it to the <CODE> |
| * SOAPHeader</CODE> object. In the following line of code, the |
| * argument to the method <CODE>addHeaderElement</CODE> is a |
