Wrong @XmlElement namspace generated from wsdl

Wrong namespace generated from the attached wsdl. The problem is in the generated GetT4DataResponseContent.java file.

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder =

)
@Generated(value = "com.sun.tools.xjc.Driver", date = "2017-06-21T04:57:52+02:00", comments = "JAXB RI vhudson-jaxb-ri-2.1-2")
public static class Nameofuser {

@XmlElement(name = "Name", namespace = "http://eeszt.gov.hu/ns/iam/ws/IAMService/ActivationMessages/v1", required = true)
@Generated(value = "com.sun.tools.xjc.Driver", date = "2017-06-21T04:57:52+02:00", comments = "JAXB RI vhudson-jaxb-ri-2.1-2")
protected Name name;

The Name field XmlElement annotation has wrong namespace.

Maybe it is a JAXB bug. Thanks for the help.
