Not right now. But I think that's an interesting idea. And I think it is
relatively easily doable.

But doing this requires much more than just a simple association,
doesn't it. You somehow have to figure out a way to propagate changes
from DOM to JAXB or JAXB to DOM without throwing away a whole tree, plus
complete change notifications to update their respective views.
I don't think maintaining two data structures in sync is the way you
want to go. If I were you, I'd probably write a wrapper that provides
typed access to DOM (you can make it generic by using
java.lang.reflect.Proxy, for example) with change notifications.
I've been thinking about something like that for some time now. Maybe I
should try to implement that...
