OK. Here's another proposal that comes from still another direction, 
and avoids all exceptions. Suppose instead of letting a child detach 
itself from its parent we let the parent element detach the child. In 
other words the signature of the detach() method would now look 
something like this:

public void detach(Element toBeDetached)
public void detach(Comment toBeDetached)
public void detach(String toBeDetached)
public void detach(ProcessingInstruction toBeDetached)
public void detach(Entity toBeDetached)

We would simply not give Document a detach() method so the root 
element could not be detached and no exceptions would ever be thrown 
by detach()?  In fact when this discussion popped up this is how I 
thought the detach() method actually worked, and I was a little 
surprised when the JavaDoc told me otherwise.
