A common request from users is how to set a value based on the existence of an element/attribute (see link below).  This enhancement request is for a solution to this problem.

http://stackoverflow.com/questions/5969265/how-do-i-assign-a-boolean-value-based-on-the-existence-of-an-element-in-jaxb

The initial proposal is to introduce 2 new annotations @XmlValueNode/@XmlValueNodes that map a value to the existence of an XML node.

Example #1

@XmlValueNode(xpath="OPEN", value="true"
public boolean isOpen() {
    return open
}

Example #2

@XmlValueNodes({
    @XmlValueNode(xpath="green", value="GREEN"),
    @XmlValueNode(xpath="yellow", value="YELLOW"),
    @XmlValueNode(xpath="red", value="RED")
})
public TrafficLightEnum getLightColour() {
    return lightColour;
}
