Do you mean simply ensure that the getContent() method returns you a real 
list where the listIterator can delete and replace ??
I've been assuming this (changing the source appropriately) as this should 
come with the newer FilterList.

Well... I'm currently trying to perform the implementation of these 
"Recipes"-like event. I have almost a kind of interface.

The most difficult bit that I foresee is in the definition of positionning:
  the ability to declare, for example, that you want to remove "this child"
  of this element is pretty limited.
In particular, in order to perform this removal, you need to go to the 
parent, iterate through the content and remove the element then.

Having something like a number for the position of an element stored in 
the element as well might ease up quite many things but I  fear this is 
out of the simplicity of JDOM.
