title: How to make a sitemap link in the page head pass the W3C validator?
body: <p>I'm trying to pass a page through the W3C Validator. The validation fails on the sitemap, which I'm including like this:</p>
  
  <pre><code>&lt;link rel="sitemap" type="application/xml" title="Sitemap" href="../sitemap.xml" /&gt;
  </code></pre>
  
  <p>The error I'm getting is: </p>
  
  <blockquote>
    <p>Bad value sitemap for attribute rel on element link: Not an absolute IRI. The string sitemap is not a registered keyword or absolute URL.</p>
  </blockquote>
  
  <p>I have been trying forever to fix it, but nothing I'm trying seems to work plus this is the recommended layout by Google and Html5 Boilerplate.</p>
  
  <p>Is there anything wrong with my syntax? Seems correct, but why is it not passing?</p>
