title: How to include xml file in xml ? <xi : include does not work
body: <p>I am trying to include some xml files in an other xml file. To do so, I used :</p>
  
  <pre><code>&lt;example xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"&gt;
  
      &lt;types xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xi="http://www.w3.org/2001/XInclude"&gt;
  
          &lt;xi:include href="file1.xml" parse="xml" /&gt;
          &lt;xi:include href="file2.xml" parse="xml" /&gt;
  
      &lt;/types&gt;
  
  &lt;/example&gt;
  </code></pre>
  
  <p>But i got this error : Unexpected attribute 'xmlns:xi'</p>
  
  <p>I don't understand why...</p>
