set_error(): Handle construction of pyexpat.error exceptions. They
now carry a 'code' attribute that gives the Expat error
number.
Added support for additional handlers for Expat 1.95.*, including
XmlDeclHandler, EntityDeclHandler, ElementDeclHandler, and
AttlistDeclHandler. Associated constants are in the 'model'
sub-object.
Added two new attributes to the parser object: ordered_attributes and
specified_attributes. These are used to control how attributes are
reported and which attributes are reported.
