jaxb: Append a value as a child node

I want to append a string value as an inner node instead as a simple string value.

So instead of having

<Node>Value</Node> 

I need to get somethind like this:

<Node>
    <Value />
</Node> 

Now I'm working with this annotations on field:

@XmlElement(name="Node")
private String node;

Is there any way to accomplish this?
