title: Using objectify to get items with a different namespace prefix
body: <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;feed xmlns="http://www.w3.org/2005/Atom" xmlns:dd="http://example.com/ns/1.0" xml:lang="en-US"&gt;
  &lt;entry&gt;
      &lt;content type="html"&gt;Hello World!&lt;/content&gt;
      &lt;dd:country_code&gt;USA&lt;/dd:country_code&gt;
  &lt;/entry&gt;
  </code></pre>
  
  <p>I would like to use lxml.objectify to access both 'Hello World!' and 'USA'.  How can it be done?  I am not concerned with efficiency, just parsimony.  I've tried everything I can think of to no avail.</p>
