@XmlType.propOrder Is not working when filed to be mapped to attributes

Question

Dear all;
I found something (may be it is a bug in the implementation) or I mistakely use it.
I have the follwoing class :
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlType;
@XmlType(name="",
propOrder={"payerName","tpaName"})
public class PayerSet {
     private String payerName;
     private String tpaName;
     public void setPayerName(String payer) {
          this.payerName = payer;
      //@XmlAttribute is disabled now
     public String getTpaName() {
          return tpaName;
     public void setTpaName(String tpa) {
          this.tpaName = tpa;
        //@XmlAttribute is disabled now
     public String getPayerName() {
          return payerName;
}and the follwing one which conatins an instance of the previous:
@XmlRootElement
public class EligibilitlyRequest{
     private PayerSet payerSet;     
     public PayerSet getPayerSet() {
          return payerSet;
     public void setPayerSet(PayerSet payerSet) {
          this.payerSet = payerSet;
}Now if I marshal an instance of EligibilitlyRequest object as shown :
     EligibilitlyRequest eligbRequestObject=new EligibilitlyRequest();
     PayerSet payeSet=new PayerSet();
     //Set payer Set---------------------------------
     payeSet.setPayerName("NCCI");
     payeSet.setTpaName("N/A");
     eligbRequestObject.setPayerSet(payeSet);
       JAXBContext ctx=JAXBContext.newInstance(EligibilitlyRequest.class);
     Marshaller m=ctx.createMarshaller();
     StringWriter sw=new StringWriter();
     m.marshal(eligbRequestObject, sw);
     System.out.print(sw.toString());
          I got the order as expected, similar to :
<eligibilitlyRequest>    
   <payerSet >
<payerName >NCCI</payerName>
< tpaName > N/A< /tpaName>
</payerSet>
</eligibilitlyRequest>Note that the order of elements inside <payerSet> is exaclty as specified in ( @XmlType(name="", propOrder={"payerName","tpaName"}) in the PayerSet class.
Now the strange thing happens when I add @XmlAttibute for the PayerSet class (removing the comment), as shown
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlType;
@XmlType(name="",
propOrder={"payerName","tpaName"})
public class PayerSet {
     private String payerName;
     private String tpaName;
     public void setPayerName(String payer) {
          this.payerName = payer;
// Now @XmlAttribute is enabled
     @XmlAttribute
     public String getTpaName() {
          return tpaName;
     public void setTpaName(String tpa) {
          this.tpaName = tpa;
// Now @XmlAttribute is enabled
        @XmlAttribute
     public String getPayerName() {
          return payerName;
<eligibilitlyRequest>
        <payerSet tpaName = "N/A" payerName = "NCCI"/>
</eligibilitlyRequest>Please, pay attention to the output order it is not as specified in teh .propOrder of @XmlType annotaion !!!!!!!!!!!!!
Can any one help me to figure out if it is a bug or I miss sometning.
Regards

Hello,
@XmlType is only for elements.
We cannot use attributes with it.
Thanks
