Jackson annotations: Dynamic Root Element name based on property value

In my Apache Wink based REST API project, I am using Jackson xml jax-rs providers. And I would like these providers to transform the POJO to XML based on Jackson/JAXB annotations. There is a requirement to dynamically set the root element name based on a property value (ie., value of a member variable). The scenarios is illustrated below:

public class Response {
    public String name;
    public List<Message> messageList;
}

public class Message {
    private String messageDetails;
    private String messageType;
}

The serialized XML will be something like:

<Response>
    <Messages>
        <Message>
             <messageDetails>abc</messageDetails>
             <messageType>Warning</messageType>
        </Message>
        <Message>
             <messageDetails>xyz</messageDetails>
             <messageType>Error</messageType>
        </Message>
    </Messages>
</Response>

But, our requirement is to dynamically change <Message> to <{messageType}>, ie., either <Warning> or <Error>. Expected serialized XML:

<Response>
    <Messages>
        <Warning>
             <messageDetails>abc</messageDetails>
        </Warning>
        <Error>
             <messageDetails>xyz</messageDetails>
        </Error>
    </Messages>
</Response>

Is it possible to provide Jackson/JAXB annotations to use value of messageType as element name. Please share your thoughts.
