title: Is <link> (not rel="stylesheet") allowed to be used in <body>?
body: <p>The new <a href="http://schema.org/" rel="noreferrer">schema.org</a> by Google, Yahoo and MS recommends usage of the <code>&lt;link&gt;</code> attribute to display the status of products in an online shop:</p>
  
  <pre><code>&lt;div itemscope itemtype="http://schema.org/Offer"&gt;
    &lt;span itemprop="name"&gt;Blend-O-Matic&lt;/span&gt;
    &lt;span itemprop="price"&gt;$19.95&lt;/span&gt;
    &lt;link itemprop="availability" href="http://schema.org/InStock"/&gt;Available today!
  &lt;/div&gt;
  </code></pre>
  
  <p>Yet, <a href="http://www.w3schools.com/html5/tag_link.asp" rel="noreferrer">according to w3schools.org</a> <code>&lt;link&gt;</code> is only allowed in head sections:</p>
  
  <blockquote>
    <p>Note:  This element goes only in the head section, but it can appear any number of times.</p>
  </blockquote>
  
  <p>I am not used to W3C style, so I was not able to understand the exact <a href="http://www.w3.org/TR/html5/semantics.html#the-link-element" rel="noreferrer">definition by W3C</a>. Can anybody help me: Is it really allowed to use <code>&lt;link&gt;</code> within the body (in HTML5, as schema.org uses HTML5 tags) or do Google, Yahoo and MS break the standard?</p>
