  <p>The <code title=rel-external><a href="#external0">external</a></code>
   keyword may be used with <code><a href="#a0">a</a></code> and <code><a
   href="#area0">area</a></code> elements.

  <p>The <code title=rel-external><a href="#external0">external</a></code>
   keyword indicates that the link is leading to a document that is not part
   of the site that the current document forms a part of.

  <p>The <code title=rel-feed><a href="#feed0">feed</a></code> keyword may be
   used with <code><a href="#link0">link</a></code>, <code><a
   href="#a0">a</a></code>, and <code><a href="#area0">area</a></code>
   elements. For <code><a href="#link0">link</a></code> elements, it creates
   a <a href="#hyperlink0" title="hyperlink link">hyperlink</a>.

  <p>The <code title=rel-feed><a href="#feed0">feed</a></code> keyword
   indicates that the referenced document is a syndication feed. If the <code
   title=rel-alternate><a href="#alternate0">alternate</a></code> link type
   is also specified, then the feed is specifically the feed for the current
   document; otherwise, the feed is just a syndication feed, not necessarily
   associated with a particular Web page.

  <p class=note>The <code title=rel-feed><a href="#feed0">feed</a></code>
   keyword is implied by the <code title=rel-alternate><a
   href="#alternate0">alternate</a></code> link type in certain cases (q.v.).

  <div class=example>
   <p>The following two <code><a href="#link0">link</a></code> elements are
    equivalent: both give the syndication feed for the current page:</p>

   <pre>&lt;link rel="alternate" type="application/atom+xml" href="data.xml"></pre>

   <pre>&lt;link rel="feed alternate" href="data.xml"></pre>
