I guess at some point we should start using namespaces for our transfer 
objects. This would be needed latest, when we do not just add an element but 
start to rename / restructure elements... Since Namespaces are usually a little 
harder to handle, I would be happy to avoid using namespaces, until is really 
becomes necessary ;-)
