Returns:

the SAX entity resolver wrapped by this object

getExternalSubset

public org.apache.xerces.xni.parser.XMLInputSource getExternalSubset(org.apache.xerces.xni.grammars.XMLDTDDescription grammarDescription)
                                                              throws org.apache.xerces.xni.XNIException,
