title: removeAtt slowly with jQuery
body: <p>I am using jQuery to select and manipulate SVG elements within the DOM. It's been tricky because I can do this adding or removing classes treating them as attributes.</p>
  
  <p>Is it possible to remove an attribute using the animation effects from jQuery?</p>
  
  <pre><code>$('rect').mouseover(function(){    
      $(this).attr('class','selected');
  });
  
  $('rect').mouseout(function(){
      $(this).removeAttr('class');
  });
  </code></pre>
