Generate XML with namespace for each element

How can I generate XML with the following schema using JAXB.

<NS1:getRatesResponse xmlns:NS1="http://mynamespaceTypes">
    <response>
        <NS2:rates xmlns:NS2="http://mynamespace">
            <currency>USD</currency>

        </NS2:rates>
        <NS3:rates xmlns:NS3="http://mynamespace">
            <currency>EUR</currency>
            
        </NS3:rates>
        <NS4:rates xmlns:NS4="http://mynamespace">
           ... etc
    </response>
</NS1:getRatesResponse>

I don't know how to tell JAXB that every new item should be NS(n+1) with the same namespace. Changing XML format is not an option, because it's external.

JAXB parses this XML correctly, but when producing using same classes it produces it like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns3:getRatesResponse
   xmlns:ns2="http://mynamespaceTypes" 
   xmlns:ns3="http://mynamespace">
  <response>
    <ns2:rates>
     <currency>EUR</currency>
     
    </ns2:rates>
    <ns2:rates>
     <currency>USD</currency>
     
    </ns2:rates>
  </response>
 </ns3:getRatesResponse>

Adding these config to my scheme solved my issue attributeFormDefault="unqualified" elementFormDefault="qualified"

For this use case I would do the following:

  1. Create a StAX XMLStreamWriter
  2. Write the getRatesResponse and response elements directly to the XMLStreamWriter
  3. Set the following property on marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true); to prevent the header from being written on each marshal call.
  4. Marshal each of the Rate objects to the XMLStreamWriter individually.
  5. On the Marshaller set an instance of NamespacePrefixMapper on it to control the namespace prefix (this currently requires the JAXB RI, support for this extension is currently being added to EclipseLink JAXB (MOXy)).
