title: Selecting different templates for a Plone tile
body: <p>on Plone, tiles are nothing but Zope browser views; we were wondering if it is possible to declare/use different templates for a tile on an simple way.</p>
  
  <p>according to <a href="https://github.com/plone/plone.tiles" rel="nofollow">plone.tiles</a> documentation you can override a template for a different context.</p>
  
  <pre><code>&lt;plone:tile
      name="sample.persistenttile"
      template="override.pt"
      permission="zope.Public"
      for="*"
      layer=".interfaces.IMyLayer"
      /&gt;
  </code></pre>
  
  <p>should we need to implement a way to mark the tiles with some interface for this? is there a different/easier solution?</p>
