+ +============================================================================+
+ | DESCRIPTION |
+ I'm writing an application that implements DeclHandler and expects to receive
+ callbacks for internal and extern entities as the DTD is parsed. However, I'm
+ only receiving calls for internal entities.
+
+ I confirmed in the debugger that, while parsing a DTD,
+ XMLDTDValidator.externalEntityDecl() is getting called and passing the call on
+ to the fDTDHandler, which is an instance of SAXParser.
+
+ That instance of SAXParser is primarly implemented by AbstractSAXParser,
+ notably internalEntityDecl(...) and externalEntityDecl(...). But, it turns out
+ that the version of externalEntityDecl(...) provided by AbstractSAXParser has
+ only 3 arguments, whereas the correct version given by
+ AbstractXMLDocumentParser has 4. Thus, the calls for external entities fall
+ through to AbstractXMLDocumentParser, which discards them.
