JAXB - How to set xmlns and prefix in child tag only

I'm using JAXB to generate a soap xml request. The current xml output that i want is this

<soapenv:Envelope 
xmlns:soapenv="http://ift.tt/sVJIaE" 
xmlns:rgw="http:/blablablablabla.org" 
xmlns:typ="http://ift.tt/1vXHont">

<soapenv:Header>

  <wsse:Security 
  soapenv:mustUnderstand="1" 
  xmlns:wsse="http://ift.tt/LRW8Ij" 
  xmlns:wsu="http://ift.tt/Hm2joJ">

       <wsse:UsernameToken wsu:Id="testToken-13">
        <wsse:Username>blbalbalL</wsse:Username>
        <wsse:Password 
        Type="http://ift.tt/1aTA7XU">1234r</wsse:Password>
     </wsse:UsernameToken>
  </wsse:Security>
 </soapenv:Header>
<soapenv:Body>
</soapenv:Body>
</soapenv:Envelope>

Until now i have generate the Envelope and Header tag but i have trouble with the Security tag.

My problem is if i try to set the xmlns to package-info.class the prefix is correct but the xmlns:wsse="blbalbla" and the xmlns:wsu="http://balbla.com" going to the root element(envelope) and not into the security tag. Here is the output that i get:

<soapenv:Envelope 
xmlns:soapenv="http://ift.tt/sVJIaE" 
xmlns:rgw="http://gr/gsis/rgwsalldata/RgWsAllData.wsdl" 
xmlns:typ="http://gr/gsis/rgwsalldata/RgWsAllData.wsdl/types/" 
xmlns:wsse="http://ift.tt/LRW8Ij" 
xmlns:wsu="http://ift.tt/Hm2joJ">
<soapenv:Header>
    <wsse:Security/>
</soapenv:Header>
<soapenv:Body/>

As you can see in the desire xml output the xmlns:wsse and xmlns:wsu namespaces are at the security tag. how can i these xmlns to security tag? and how can the UsernameToken tag should build?

package-info.class

@XmlSchema(
    namespace = "http://ift.tt/sVJIaE",
    xmlns = { @XmlNs(prefix="soapenv", namespaceURI="http://ift.tt/sVJIaE"),
              @XmlNs(prefix="rgw", namespaceURI="http://blabalbalbal.org"),
              @XmlNs(prefix="typ", namespaceURI="blablaba/types/"),
              @XmlNs(prefix="wsse", namespaceURI="http://ift.tt/LRW8Ij"),
              @XmlNs(prefix="wsu", namespaceURI="http://ift.tt/Hm2joJ")},
    elementFormDefault = XmlNsForm.QUALIFIED)
