Content has a detach() that returns type Content, which means you can't
Element detached = otherElt.detach();
You have to cast:
Element detached = (Element) otherElt.detach();
With Java 5, the call to detach() could return Element specifically. A
docType.getParent() could return Document instead of Parent. A
text.getParent() likewise could return Element.
Covariant return types let you return specific types rather than
superclass types, and it's nice because beginners don't even realize
there's this fancy thing going on -- it just makes sense.
