title: XML: do child nodes inherit parent's namespace prefix?
body: <p>Assume the following XML document:</p>
  
  <pre><code>&lt;root xmlns:foo="..."&gt;
    &lt;foo:parent&gt;
      &lt;child/&gt;
    &lt;/foo:parent&gt;
  &lt;/root&gt;
  </code></pre>
  
  <p>does <code>child</code> element belong to a namespace that corresponds to the prefix <code>foo</code>? Just like in case <code>&lt;foo:child/&gt;</code>?</p>
