body: <p>I have those open graph tags on <a href="http://demo.outsourceproject.co.uk" rel="nofollow">demo.outsourceproject.co.uk</a>:</p>
  
  <pre><code>&lt;meta content='Demo Shop' property='og:title'&gt;
  &lt;meta content='restaurant' property='og:type'&gt;
  &lt;meta content='http://demo.lvh.me:3000/images/screenshots/layouts/005_small.jpg' property='og:image'&gt;
  &lt;meta content='http://demo.lvh.me:3000/categories/15-starters' property='og:url'&gt;
  &lt;meta content='demo@ordys.co.uk' property='og:email'&gt;
  &lt;meta content='02010203040' property='og:phone_number'&gt;

  &lt;meta content='W1H 1DP' property='og:postal-code'&gt;
  &lt;meta content='United Kingdom' property='og:country-name'&gt;
  </code></pre>
  
  <p>When I <a href="https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fdemo.outsourceproject.co.uk%2Fcategories%2F13-starters" rel="nofollow">validate it with</a> with facebook object debugger it reports warnings like:</p>
  
  <pre><code>Extraneous Property:Objects of this type do not allow properties named og:email.
  </code></pre>
  
  <p>Do you have any idea why og:email, og:locality etc it is not allowed for og:type=restaurant?</p>
  
  <p>Thanks,</p>
