Help needed to resolve there is no attribute X errors..

Question

On my website http://www.dorffdesign.nl/ there is a problem. Ive put the FB Like button there and it worked fine for a while. But now its gone. So ive run
http://validator.w3.org/ on it and came up with the next errors:
========================================================================================== ==============================================
  Line 232, Column 32: there is no attribute "data-href" <div class="fb-like" data-href="http://www.dorffdesign.nl/" data-send="true" da… ✉  
  Line 232, Column 71: there is no attribute "data-send" …http://www.dorffdesign.nl/" data-send="true" data-width="450" data-show-faces=… ✉  
  Line 232, Column 89: there is no attribute "data-width" …orffdesign.nl/" data-send="true" data-width="450" data-show-faces="true"></div> ✉  
  Line 232, Column 111: there is no attribute "data-show-faces" …orffdesign.nl/" data-send="true" data-width="450" data-show-faces="true"></div>
========================================================================================== ===============================================
In dreamweaver ive use this code for the FB likke button:
<div id="fb-root"></div>
<script>(function(d, s, id) {
  var js, fjs = d.getElementsByTagName(s)[0];
  if (d.getElementById(id)) return;
  js = d.createElement(s); js.id = id;
  js.src = "//connect.facebook.net/nl_NL/all.js#xfbml=1";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
========================================================================================== ===========
<div class="fb-like" data-href="http://www.dorffdesign.nl/" data-send="true" data-width="450" data-show-faces="true"></div>
I really want to solve this so im hoping if you can point me into the right direction.
Regards

You can either ignore those errors (since they have no impact on your page's functionality) or you can use DW to convert your page to an HTML5 doctype (File > Convert > HTML 5, and then the errors will go away.
