title: What is the difference between properties and attributes in HTML?
body: <p>After the changes made in jQuery 1.6.1, I have been trying to define the difference between properties and attributes in HTML.</p>
  
  <p>Looking at the list on the <a href="http://blog.jquery.com/2011/05/12/jquery-1-6-1-released/" rel="noreferrer">jQuery 1.6.1 release notes</a> (near the bottom), it seems one can classify HTML properties and attributes as follows:</p>
  
  <ul>
  <li><p>Properties: All which either has a boolean value or that is UA calculated such as selectedIndex. </p></li>
  <li><p>Attributes: 'Attributes' that can be added to a HTML element which is neither boolean nor containing a UA generated value.</p></li>
  </ul>
  
  <p>Thoughts?</p>
