element1.setContent( element2.removeContent()); should do that (but the no arg
removeContent() is only in the latest cvs), if it doesn't then that's a bug
that needs to be fixed.

setContent was never suppose to automagically detach nodes already attached
to another parent. There have been discussions about whether add/setContent
should automagically detach nodes, but the general feeling is that this makes
it to easy for logic error to go unnoticed.
