How to include version attribute in output when marshalling

Below is the valid xml .

<Input xsi:noNamespaceSchemaLocation="some.xsd" 
       version="V16.2" 
       xmlns:xsi="http://ift.tt/ra1lAU">
<SITE>com</SITE>
<LANGUAGE>SV</LANGUAGE>
</Input>

The XML which I got from XSD to JAXB then XML using Marshallar is:

<Input xsi:noNamespaceSchemaLocation="some.xsd" 
       xmlns:xsi="http://ift.tt/ra1lAU">
       <SITE>com</SITE>
    <LANGUAGE>SV</LANGUAGE>    
</Input>

SO the problem is that version="V16.2" is missing in the second generated XML, so the consuming code throws an error.

My Marshaller property

Marshaller marshaller= jaxbContext.createMarshaller();
            marshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);
            marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
            marshaller.setProperty(Marshaller.JAXB_NO_NAMESPACE_SCHEMA_LOCATION, "some.xsd");

Can anyone help me figure out how to include a version attribute?
