[jdom-interest] Life or death of the Parent interface

[Alex Rosen]

"Its main purpose right now could be described as a generic type for 
setParent() to take and getParent() to return.  There's also the
benefit 
when learning the API that you quickly see how Document and Element 
share a core set of methods.  Those benefits are nice, but really not 
critical."

Agreed. I think that if there's any code breakage for existing users,
these are not great enough benefits to argue for keeping it.
