[class Text implements Comparable?]

I don't think it should be added at all, because the "natural order" of xml
nodes is not very clear. What can be done, is writing (perhaps in
jdom.contrib) a class that has many Comparator objects. Something like:

class JDOMComparators {
    public final static Comparator ElementTextComparator=new Comparator() {
        public int compare(Object o1, Object o2) {
            Element e1=(Element)o1;
            Element e2=(Element)o2;
            return e1.getText().compareTo(e2.getText());
        }
    }
    public final static Comparator TextComparator ...
    // etc.
}

If anyone here thinks it's a good idea, I may do it.


 - Noam.
