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.")
