* @brief ACEXML_EntityResolver
*
* If a SAX application needs to implement customized handling for
* external entities, it must implement this interface and register an
* instance with the SAX driver using the setEntityResolver method.
*
* The XML reader will then allow the application to intercept any
* external entities (including the external DTD subset and external
* parameter entities, if any) before including them.
*
* Many SAX applications will not need to implement this interface,
* but it will be especially useful for applications that build XML
* documents from databases or other specialised input sources, or for
* applications that use URI types other than URLs.
