Error page 404 and RSS autodiscovery

Had a real laugh at Marks 404 error page [1]. The correct URL would be this [2]. Actually I was looking for his ideas on the RSS autodiscovery feature [3]. The aim is to not give a specific RSS location but simply the site address. His autodiscovery script will detect the RSS source link:

<link rel=\”alternate\” type=\”application/rss+xml\” title=\”RSS\” href=\”http://circle.ch/blog/b2rss.php\”>

Unless you have that link tag in your (x)html source, the result of autorss.py is the passed URL.
