I suspect that enhancing JDOM with Generics is not as trivial as one 
would think especially when one wants to go the whole way. One of the 
reasons is erasure:
An example:

In AttributeList there are these two methods:
    void add(int,Attribute);
    public void add(int,Object);


Enhancing AttributeList with Generics would result in something like:
AttributeList<A extends Attribute> {
    void add(int,Attribute);
    public void add(int,A);
}

which is not allowed. Reducing the code to
AttributeList<A extends Attribute> {
    public void add(int,A);
}
is possible but will break some code. I worry that a "JDOM 1.5" can't be 
drop in replacement...
