While there is nothing wrong with that result, you may want to get rid of most or all of JAXBElements and thus make your code smaller, cleaner and easier to use.
The first solution might seem to be using <xjc:simple/> configuration as shown in http://weblogs.java.net/blog/kohsuke/archive/2006/03/why_does_jaxb_p.html.
It is usually not the case with WCF services and so the <xjc:simple/> method does not help.
The actual solution is found in https://jax-ws.dev.java.net/guide/Customizations_for_WCF_Service_WSDL.html.
Just use generateElementProperty="false".
Quote from the solution:
When processing a WCF service WSDL, it is recommended that the generateElementProperty customization be set to false in <jaxb:globalBindings>
The generateElementProperty attribute was introduced in JAXB 2.1.
