Hi. HTML 5 says; "If the alternate keyword is used with the type attribute set to the value application/rss+xml or the value application/atom+xml, then the user agent must treat the link as it would if it had the feed keyword specified as well." -- http://www.whatwg.org/specs/web-apps/current-work/#link-type I believe this in error. Atom, at least (I expect this also holds for RSS), is useful for representing more things than just feeds. It's really a generic packaging mechanism. For example, one might do the equivalent of MHTML[1] using Atom, and link such a document to an HTML page with rel="alternate". But it isn't a feed, and it isn't something you'd want syndication tools to auto-discover as a feed, since that will just confuse users. In addition, the media type on link is non-authoritative, meaning that feed-semantics would be inferred before it was even ascertained that the would-be representation was actually an Atom or RSS document. Thanks. [1] http://www.ietf.org/rfc/rfc2557.txt Mark.
