JAXB and property ordering with list of elements

I am using JAXB to unmarshall xml file. here is my code for the element feature, but I wanna have a special order of the elements in the element feature, like this

<feature>
  <name>2D Polynomial Approximation of Log of ConstantQ</name>
  <active>false</active>
  <attribute>50</attribute>
  <attribute>20</attribute>
  <attribute>10</attribute>
  <attribute>10</attribute>
</feature>

I checked some tutorial of @XmlType(propOrder = {}), but I cannot find a way to order with list of elements like the attribute elements here.

here is my codes

@XmlRootElement(name = "feature")
@XmlType(propOrder = {"name", "active","attribute"})
public class Feature{

    String name;

    boolean active;

    List<String> attributes = new LinkedList<String>();

    /**
     * name element of feature element
     * @return
     */
    @XmlElement(name = "name")
    public final String getName(){
        return this.name;
    }

    public final void setName(String name){
        this.name = name;
    }

    /**
     * active element
     * @return
     */
    @XmlElement(name = "active")
    public final boolean getActive(){
        return this.active;
    }

    public final void setActive(boolean active){
        this.active = active;
    }

    /**
     * attribute elements
     * @return
     */
    @XmlElement(name = "attribute")
    public final List<String> getAttributes(){
        return this.attributes;
    }

    public final void setAttributes(List<String> attributes){
        this.attributes = attributes;
    }
}

It always throw out exception, since I only define one attribute in propOrder. But since the attribute is multiple, could be one or more, I do not have any idea to implement it. Or do you know some other way to order the elements

Thanks for your help in advance

The propOrder is based on the field/property name and not the XML element name. So you should have

@XmlType(propOrder = {"name", "active","attributes"})

For More Information
