title: jaxb prints unknown source when generating xbrl schema
body: <p>I used jaxb before to generate java code from a xsd to easily prints xml files afterwards.</p>
  
  <p>Now I want to use jaxb to generate a xbrl report. I use xjc as follows:</p>
  
  <pre><code>xjc.exe "http://www.nltaxonomie.nl/10.0/report/bd/entrypoints/bd-rpt-ob-aangifte-2016.xsd" -verbose -d "D:\Test\src" -p xso.bd.aangifte2016
  </code></pre>
  
  <p>The output is:<code>
  parsing a schema...
  compiling a schema...
  [INFO] generating code
  unknown location</code></p>
  
  <p>Result: no sources are generated </p>
  
  <p>It does not say which location is unknown. I think xjc cannot deal with relative paths in the xsd, but I am not sure about it. </p>
  
  <p>Does anyone know how to generated java code for this xsd?</p>
  
  <p>Thanks.</p>
