+XML::Parser::Expat, which is a lower level interface to James Clark's expat
+library.  Each call to one of the parsing methods creates a new instance of
+XML::Parser::Expat which is then used to parse the document.  Expat options
+may be provided when the XML::Parser object is created.  These options are
+then passed on to the Expat object on each parse call.  They can also be given
+as extra arguments to the parse methods, in which case they override options
+given at XML::Parser creation time.")
