title: In Polymer 1.0 how can I databind to a boolean property of an element?
body: <p>How can I bind to a boolean property of an element. It seems this</p>
  
  <pre><code>&lt;my-element a-property-of-type-boolean='{{someBoolean}}'&gt;&lt;/my-element&gt;
  </code></pre>
  
  <p>does not Work, but I also cant find out how to bind to it when it is exposed like this:</p>
  
  <pre><code>&lt;my-element a-property-of-type-boolean&gt;&lt;/my-element&gt;
  </code></pre>
  
  <p>It seems an option is to set the type to Object instead of Boolean, but I am not sure how valid this approach is</p>
  
  <p>Thanks :-)</p>
