16   *  <code>DOMErrorHandler</code> is a callback interface that the DOM 
17   * implementation can call when reporting errors that happens while 
18   * processing XML data, or when doing some other processing (e.g. validating 
19   * a document). A <code>DOMErrorHandler</code> object can be attached to a 
20   * <code>Document</code> using the "error-handler" on the 
21   * <code>DOMConfiguration</code> interface. If more than one error needs to 
22   * be reported during an operation, the sequence and numbers of the errors 
23   * passed to the error handler are implementation dependent. 
24   * <p> The application that is using the DOM implementation is expected to 
25   * implement this interface.
