As Jon Udell discovered, a solution already exists which is simplicity onto itself. Channel elements have an "about" element which specify where the rss feed can be found. If present and different, then readers should follow. [Sam Ruby]

Only sometimes the RSS 1.0 people seem to forget they're using RDF. Because putting the URL of the RDF file itself in the about attribute is of the channel is incorrect. The about attribute denotes what the statements are about. In this case it should be the same as the link element. F.e. the title in my RSS 2.0 file is “Sjoerd Visscher's weblog”, not “a feed for Sjoerd Visscher's weblog”. A feed describes a webpage, not itself.
