title: XML default namespace issue
body: <p>Suppose I have the following XML schema file and the following XML document file. I have two questions,</p>
  
  <ol>
  <li><p>Since there is no target name space specified in XML Schema file, what namespace will Information element in?</p></li>
  <li><p>In the XML document file, when using Information, which namespace does it belong to? Please notice in this case, I do not refer to XML Schema file from the XML document file.</p></li>
  </ol>
  
  <p>XML Schema file:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
  elementFormDefault="qualified"&gt;
  &lt;xs:element name="Information" type="xs:string"/&gt;
  &lt;/xs:schema&gt;
  </code></pre>
  
  <p>XML document file:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;Information&gt;Hello XML&lt;/Information&gt;
  </code></pre>
  
  <p>thanks in advance,
  George</p>
