I dont see any reason _ALL_ JDOM classes needs to implement a single
interface. I woud have several interfaces/base classes describing what an 
object can do.

For exsample a IJDOM interface coud define a public clone() metod without
trows cloneable since all JDOM objects are clonebale.
A (I)JDOMContent interface/base-class coud extend/implement IJDOM and
add a detach() and getParent() metod and all classes that are legal 
content of Document or Element woud extend/implement this. 
Attributes are handled separate from content and woud not 
exstend/implement (I)JDOMContent.


Just my 2 cents.
