[X4U] new safari and RSS feeds

[Kansas Territory]

I've noticed in Safari 2.0 if I go to a web page, like www.cnn.com    
for example,  in Safari's address bar, to the right is an "RSS" icon.  
Clicking on this will display the RSS feed for that page.    Very  
handy I thought.
I've created a few RSS feeds for a few web pages.   But how do I get  
Safari to realize this automatically like it does with the CNN.com  
page.  ?

Any suggestions would be appreciated.
