If you want to move an apple on one tree to another tree, what do you
do?  You remove the apple from the first tree, then add it to the second
tree.  Same as in JDOM.  

If you try to just add the apple (or Element) to the second tree or to a
new place on the tree it rightfully complains that it can't be attached
to two places.  :-)

So:

elt.getParent().removeContent(elt);  // remove
root.addContent(elt);                // add

Note that removeContent() is deprecated but I'm going to push to bring
it back.  You can also do:

elt.getParent().getChildren().remove(elt);

If you want a copy added, then you have clone() or getCopy().
