title: Magento: Add content block at the end of the structual block "content"
body: <p>I'm trying to add a content block to Magento, which should be visible on every side below the main content. I want to archive this with a custom extension, so I can copy this extension and it workes without touching core design files.
  My extension includes the following layout update:</p>
  
  <pre><code>&lt;default&gt;
      &lt;reference name="content"&gt;
          &lt;block type="mymod/blockname" name="myblockname" after="-" template="mymod/block.phtml"/&gt;
      &lt;/reference&gt;
  &lt;/default&gt;
  </code></pre>
  
  <p>My problem is, that the attribute <code>after="-"</code> is not working. The block always showes up at the top of the content block. Seems <code>before</code> and <code>after</code> have no consequence.
  If I move the block to i.e. footer, the attributes <code>before</code> and <code>after</code> are working fine.</p>
  
  <p>How can I place my block at the bottom of block "content"</p>
