Edit JAXB generated annotation using annox and add namespace in param

Question

I do have the following annotation in a JAXB generated class

@XmlType(name = "MessageInfoType", propOrder = {
    "debugTraceBoolean",
    "clientHostnameString",
    "endUserIPAddress"
})

Need to produce the following annotation in JAXB class with custom binding..i.e is need to edit the above annotation and add a namespace using annox as below type.

        @XmlType(name = "MessageInfoType", propOrder = {
            "debugTraceBoolean",
            "clientHostnameString",
            "endUserIPAddress"
        }, namespace="urn:expedia:e3:data:messagetypes:defn:v4")

my xjb file is:

  <jaxb:bindings schemaLocation="../../serviceDescription/atlantis/common/com.expedia.e3.data.messagetypes.v4.xsd">

    <jaxb:bindings node="//xs:complexType[@name='MessageInfoType']">
        <annox:annotate target="field">
            <annox:annotate annox:class="javax.xml.bind.annotation.XmlType" 
                   namespace="urn:expedia:e3:data:messagetypes:defn:v4"/>
        </annox:annotate>
    </jaxb:bindings>
  </jaxb:bindings>

If you try to add an annotation which already exists (same location, same annotation class), this will modify an existing annotation rather than add a second one. I am not sure at the moment, if this will override all the attributes or merge new ones, but it's definitely worth trying.

Update:

I've rechecked this. Indeed, it is implemented (should be of version 0.6.4, I've just checked with 0.6.5-SNAPSHOT).

Check this sample:

https://svn.java.net/svn/jaxb2-commons~svn/basics/trunk/tests/annotate/src/main/resources/bindings.xjb

Here's the binding:

    <jaxb:bindings node="xs:complexType[@name='issueJIIB39CType']/xs:attribute[@name='test']">
        <annox:annotate target="field">
            <annox:annotate annox:class="javax.xml.bind.annotation.XmlAttribute" required="false"/>
        </annox:annotate>
    </jaxb:bindings>

If this binding is present, you'll get:

@XmlAttribute(name = "test", required = false)
protected String test;

If not it will be like this:

@XmlAttribute(name = "test", required = true)
protected String test;

So, as I said if you add an annotation at the very same place and the very same class, they will be merged.
