title: Element link is missing required attribute property
body: <pre><code>&lt;!DOCTYPE html&gt;
  ...
  &lt;link rel='stylesheet' id='basecss-css' href='http://www.someurl.com/modules/14ce1e21/peadig-eucookie.css' type='text/css' media='all' /&gt;
  </code></pre>
  
  <p>Why is the validator (<a href="http://validator.w3.org/">http://validator.w3.org/</a>) rejecting this? What attribute is "required" that I am not aware of?</p>
  
  <p>The error:</p>
  
  <blockquote>
    <p>Error Line 408, Column 142: Element link is missing required attribute
