title: rss and atom content type
body: <p>I have a problem with my feed's content-type:</p>
  
  <p>When I set the <code>content-type</code> to <code>"application/rss+xml"</code> or <code>"application/atom+xml"</code> the <strong>Firefox</strong> will render it current (and displays the default subscribe page), but the <strong>Chrome</strong> renders it as <code>"text/plain"</code>. When I change the <code>content-type</code> to <code>"text/xml"</code> or <code>"application/xml"</code> both <strong>Firefox</strong> and <strong>Chrome</strong> render it as a <strong>xml</strong> document (and <strong>Firefox</strong> will not show the Subscribe page).</p>
  
  <p>Have you any idea or suggestion? Which content-type should I use for <strong>rss.xml</strong> and <strong>atom.xml</strong>?</p>
