  46  * <p>If a SAX application needs to implement customized handling

  49  * {@link org.xml.sax.XMLReader#setEntityResolver setEntityResolver}
  50  * method.</p>
  51  *
  52  * <p>The XML reader will then allow the application to intercept any
  53  * external entities (including the external DTD subset and external
  54  * parameter entities, if any) before including them.</p>
  55  *
  56  * <p>Many SAX applications will not need to implement this interface,
  57  * but it will be especially useful for applications that build
  58  * XML documents from databases or other specialised input sources,
  59  * or for applications that use URI types other than URLs.</p>
  60  *
