Is there any benefit of using html5shim library over document.createElement('header')?

Question

What is difference between using

<!--[if IE]>
<script>
  document.createElement('header');
  document.createElement('footer');
  document.createElement('section');
  document.createElement('nav');
</script>
<![endif]-->

instead

<!--[if lt IE 9]>
<script src="//html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->

Answer 1

I believe that the HTML shim library also includes the IE print Protector
