Some PEPs, probably those formatted with reST, do not display any more in my IE 6 (Version 6.0.2600.0000), for example http://www.python.org/peps/pep-0301.html and http://www.python.org/peps/pep-0258.html. It says: Use of default namespace declaration attribute in DTD not supported. Error processing resource 'http://www.python.org/peps/pep-0258.html'. Line 8, Position 17 <html lang="en"> Thomas
