title: GPX file: The matching wildcard is strict, but no declaration can be found for element
body: <p>I am working with GPX files and I am parsing them with Java. I am using javax.xml.validation.Validator to make sure they conform to the GPX schema. The thing is, one of my files ends with: </p>
  
  <pre><code>&lt;TopoFusion:color&gt;ff0000&lt;/TopoFusion:color&gt;
  &lt;TopoFusion:graph&gt;0&lt;/TopoFusion:graph&gt;
  &lt;/gpx&gt;
  </code></pre>
  
  <p>and this TopoFusion element is apparently not defined in the GPX schema, causing the validation to fail. However, the file is valid if I am to ignore this element. Any idea how I can overcome this problem ? I want to make it generic though, not simply ignore TopoFusion element as it can be anything there.</p>
  
  <p>Hope my question is clear. Any help will be much appreciated.</p>
  
  <p>Regards,</p>
