title: PersistenceException -Duplicate annotation of name in Simple XML deserialization
body: <p>I test simple xml tutorial from this <a href="http://simple.sourceforge.net/download/stream/doc/examples/example7/example7.zip" rel="nofollow">link</a>. I change the xml file like this.</p>
  
  <pre><code>&lt;example xmlns:ns1="http://www.blah.com/ns/a"&gt;
    &lt;a&gt;
      &lt;b&gt;
          &lt;x&gt;abc&lt;/x&gt;
        &lt;ns1:x&gt;blah&lt;/ns1:x&gt;
      &lt;/b&gt;
    &lt;/a&gt;
  &lt;/example&gt;
  </code></pre>
  
  <p>and I add the following coding into the <code>Example7</code> class.</p>
  
  <pre><code>   @Path("a/b")
     @Element(name = "x")
     private String x_;
  </code></pre>
  
  <p>I got this exception <code>PersistenceException : Duplicate annotation of name 'x' on field 'x'</code>. I would like to know how to overcome this exception.</p>
  
  <p>Thanks.</p>
