title: Google SDTT: "The property 'availability' is not recognized by Google for an object of type Product"
body: <p>Situation: need to add the <code>availability</code> property to a product page.</p>
  
  <p>Schema.org recommends this format for Microdata:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;link itemprop="availability" href="http://schema.org/InStock" /&gt;In stock
  </code></pre>
  
  <p>I'm combining it with the code on our site:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;li&gt;
      &lt;i class="fa fa-check-square-o"&gt;&amp;nbsp;
          &lt;link itemprop="availability" href="http://schema.org/InStock"&gt;
          &lt;span&gt;In Stock&lt;/span&gt;
      &lt;/i&gt;
  &lt;/li&gt;
  </code></pre>
  
  <p>Problem: Google Structured Data Testing Tool reports:</p>
  
  <blockquote>
    <p><code>http://schema.org/InStock</code> (The property <code>availability</code> is not recognized by Google for an object of type <code>Product</code>.)</p>
  </blockquote>
  
  <p>Is this a code issue?<br>
  Or am I missing some Schema/Google "wrapper" for the <code>availability</code> property?</p>
