Anotaciones JAXB para enumeraciones

I have the following enum definition:

public enum MyEnumeration{

  ENUM_ONE("1","foo"),
  ENUM_TWO("2","bar");

  private String code;
  private String description;

  public String getDescription()
  {
     return this.description;
  }

  public String getCode()
  {
     return this.code;
  }    
}

And I want to annotate it with Jaxb annotations so it will be marshalled into the following xml.

<myenumeration>
  <code>...</code>
  <description>...</description>
</myenumeration>

I've tried several approaches, but wasn't succesful. Any ideas? Thanks in advance!
