title: HTML <!doctype html public "">
body: <p>One of the new doctype declarations can be specified as:</p>
  
  <pre><code>&lt;!doctype html&gt;
  </code></pre>
  
  <p>But recently I came across one which was slightly different (view source on <a href="http://html5boilerplate.com/" rel="noreferrer">http://html5boilerplate.com/</a>):</p>
  
  <pre><code>&lt;!doctype html public ""&gt;
  </code></pre>
  
  <p>But I couldn't figure what is it for, public part?</p>
  
  <p>Thanks.</p>
