title: link rel="script" usage
body: <p>I am reading through the <strong><a href="http://www.w3.org/TR/2002/REC-xhtml1-20020801/dtds.html#a_dtd_XHTML-1.0-Strict" rel="nofollow noreferrer">XHTML 1.0 Strict Doctype</a></strong> and found out that there's a value of <code>"script"</code> for the <code>rel</code> attribute on the <code>link</code> element.</p>
  
  <pre><code>&lt;link rel="script" href="..." /&gt;
  </code></pre>
  
  <p>I tried using this tag to link external JS files, but Safari does not even load the file. So what can the tag be used for?</p>
  
  <p><strong>Update:</strong></p>
  
  <p>After rereading the DTD, it doesn't exactly list out valid values for the <code>rel</code> attribute. The <code>'script'</code> value appears only as an example on a comment. Thus, this may or may not be implemented in all browser.</p>
