title: Using aria attributes on elements in react
body: <p>I have the following render method:</p>
  
  <pre><code>render: function () {
    return (
      React.createElement('div', {className: 'modal', id: 'errorModal', tabIndex: '-1', role: 'dialog', ariaHidden: 'true', dataBackdrop: 'false', style: {marginTop: '30px'}}, 'text')
    )
  }
  </code></pre>
  
  <p>That gives me error:</p>
  
  <blockquote>
    <p>react.js:20541 Warning: Unknown props <code>ariaHidden</code>, <code>dataBackdrop</code> on
     tag. Remove these props from the element. For details, see
        in div (created by Constructor)
        in Constructor</p>
  </blockquote>
  
  <p>How could I solve this? Documentation says that I can use these attributes. Lowercase does not work either. I don't want to use jsx.</p>
