[jdom-interest] Convoluted Document Construction on b10

[Jason Hunter]

It's well understood.  The reason is that Java doesn't have covariant 
return types so the new Parent interface's addContent() methods returns 
Parent and the Element implementation can't return the more specific 
type of Element.  You can do it in J2SE 1.5.

Options are: rip out the Parent interface, write an addContent(Parent) 
method as a nasty hack, keep it this way and have a J2SE 1.5 version.
