title: How to set cart template based on product type?
body: <p>I have a new product type and when on cart page, I need to show a different cart.phtml for that custom product type. If I set like this, all product types will use this new cart.phtml. </p>
  
  <pre><code>&lt;checkout_cart_index&gt;
     &lt;reference name="checkout.cart"&gt;
        &lt;action method="setTemplate"&gt;
           &lt;template&gt;mymodule/checkout/cart.phtml&lt;/template&gt;
        &lt;/action&gt;
     &lt;/reference&gt;
  &lt;/checkout_cart_index&gt;
  </code></pre>
  
  <p>However, if I use this, it doesn't work.</p>
  
  <pre><code>&lt;PRODUCT_TYPE_custom module="catalog"&gt;
     &lt;reference name="checkout.cart"&gt;
        &lt;action method="setTemplate"&gt;
           &lt;template&gt;mymodule/checkout/cart.phtml&lt;/template&gt;
        &lt;/action&gt;
     &lt;/reference&gt;
  &lt;/PRODUCT_TYPE_custom&gt;
  </code></pre>
  
  <p>Is there any other way? Thanks in advance.</p>
