title: XQuery - Error - XML-20201
body: <p>I am trying to run an XQuery file using Saxon. I keep getting this error when the code execute. The funny thing is the XQ works fine when i debug it as a standalone file in XMLSpy. When i deploy it and run my application, it throws the following exception:</p>
  
  <pre><code>Error reading datasource: XQuery Processor Exception: Exception while calling Saxon: org.xml.sax.SAXParseException: : XML-20201: (Fatal Error) Expected name instead of :.; SystemID: ; Line#: 8; Column#: -1; Cause: : XML-20201: (Fatal Error) Expected name instead of :. 
  </code></pre>
  
  <p>I am not able to figure out where the error happens and what i can do to fix it. My only guess is the the input XMLs to XQuery might be an issue. But i am not sure which line in the XQuery is failing. As line 8 is commented line!</p>
  
  <p>Is there any way to narrow it down, where the error is coming from?</p>
