title: Magento dynamic text in layout xml file using addText
body: <p>I currently have this:</p>
  
  <pre><code>    &lt;block type="core/text" name="top.address" as="topAddress"&gt;
          &lt;action method="addText"&gt;&lt;text&gt;PO BOX 1124, Rockdale, Sydney, NSW 2216, Australia&lt;/text&gt;&lt;/action&gt;
      &lt;/block&gt;
  </code></pre>
  
  <p>But, when I need to update address, I have to do it manually here in the layout file. I want to pull address from store config ( <strong>general/store_information/address</strong> ) so, I can update everywhere on the site from one location easily.</p>
  
  <p>I guess it can be done directly on the template like this:</p>
  
  <pre><code>&lt;?php echo Mage::getStoreConfig('general/store_information/address') ?&gt;
  </code></pre>
  
  <p>But I want to try with layout, is it possible?</p>
  
  <p>Thanks.</p>
