[jdom-interest] Extending Element

[Charles Havranek]

Here's the class definition - can you give an example as the right way 
to extend it ? :)

public class xdeElement extends org.jdom.Element{
   public xdeElement() {
   }
   public static void main(String[] arg){
       org.jdom.Element name = new org.jdom.Element("name");
       name.setAttribute("language", "English");
       xdeElement tmp= new xdeElement(name);
   }
   /** Create a new Element based on existing Element */
   public xdeElement(org.jdom.Element existingElement){
       super.setContent(existingElement.getContent());
       System.out.println("Original: "+ 
existingElement.getAttributeValue("language"));
       System.out.println("This: "+ this.getAttributeValue("language"));
       System.out.println("Super: "+ super.getAttributeValue("language"));
   }
