[jdom-interest] Document serialization?

Jason and Philip,
    Found the issue. Part of what my app does is merge two different xml 
trees, and deep in the bowels of doing so, calls getAttributes() on 
elements scheduled for replacement. This returns a PartialList, which is 
in turn put onto the elements that are replacing them with a 
setAttributes call. This 'corrupts' the Element List tree with 
PartialLists, and hence breaks serialization. I've patched my code to 
convert that PartialList to an ArrayList, before calling setAttributes, 
however, it might be an potential issue for others.
