JAXB: using anonymous namespace (no prefix)

Question

I am using a namespace for my JAXB serialized object, so that the first part looks like that:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:DataRecords xmlns:ns2="http://test.org/DataRecord/" StartProcessingTime="2010-05-20T12:34:37.123Z" ChargingDataVersion="1.0">
    <Item>
....As you can see JAXB uses the default Prefix "ns2" for assigning the DataRecords node to the namespace. Due to a special request I need
to use an anonymous namespace with no prefix, something like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<DataRecords xmlns="http://test.org/DataRecord/" StartProcessingTime="2010-05-20T12:34:37.123Z" ChargingDataVersion="1.0">
    <Item>
....If I got the XML specifications right this should do the job as well, as long as only one namespace is used. Using JAXB I only recognized the
possibility to change the prefix via a property of the marshaller and a custom prefix manager. But it seems impossible to abandon the prefix
completely (returning null or an empty string in the custom prefix manager falls back to the default name prefixes)
any idea?

This seems wrong to me. I've filed Bug 2400119 to get this looked into by development.
I'd expect any document with an appropriate qualified name to be found by your XPath expression, irrespective of whether syntactically one of the documents happened to use the default namespace syntax.
