Hi Matthias,

sorry for not being clearer so far, although I'm still not an 
authoritative source on this matter, I'd conclude my research into this 
field: there is no specification or RFC.

You can use the "link" element to relate a document to various other 
resources. If you use its "rel" attribute to define the relation to be 
of type "alternate", you can link to whatever you like. Your problem 
than is conforming clients, who know what to make of this additional 
metadata. In the case of RSS feeds, there seems to be an implicit 
standard, for clients to allow suitable access to the referenced 
resource.

But all this theory is useless in the jungle called "www". So my 
practical advise would be to use the "link" element. It seems most 
elegant and is understood by modern browsers. And to also use a regular 
link (an anchor) inside the page, accompanied by one of those orange 
icons for better recognition. And as a third option I'd include some 
service like "addthis" <http://www.addthis.com> to show off, that you 
know your way around the web 2.0 and because it allows your users to 
conveniently add your RSS feed also to web based feed readers.

Good luck.
