title: @xmlSchema annotation use with jaxb
body: <p>I can't get to show in a xml file all the parameters configured with the @xmlSchema annotation at package level. For example, if I set: </p>
  
  <pre><code>@javax.xml.bind.annotation.XmlSchema (               
      xmlns = { 
              @javax.xml.bind.annotation.XmlNs(prefix = "com", 
                       namespaceURI="http://es.indra.transporte.common"),
  
              @javax.xml.bind.annotation.XmlNs( prefix = "xsi",
                       namespaceURI="http://www.w3.org/2001/XMLSchema-instance"),
  
              @javax.xml.bind.annotation.XmlNs( prefix = "ns2",
                       namespaceURI="http://es.indra.transporte.configuration"),             
             },    
      location = "http://es.indra.transporte.configuration StationNetwork.xsd",
      elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED        
  )
  package es.indra.transporte.central.thalesinterface.common.beans;
  </code></pre>
  
  <p>I expect to see something like:</p>
  
  <pre><code>&lt;stationNetwork xmlns:ns2="http://es.indra.transporte.configuration"
                  xmlns:com="http://es.indra.transporte.common"
                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xsi:schemaLocation="http://es.indra.transporte.configuration StationNetwork.xsd"&gt;
  </code></pre>
  
  <p>but I get the following output:</p>
  
  <pre><code>&lt;stationNetwork xmlns:com="http://es.indra.transporte.common"&gt;
  </code></pre>
  
  <p>What I'm doing wrong? How can I get the expected output?</p>
