That is definitely going to be useful. Thanks a lot Bruno!

Well, I just couldn't find a way with my (quite tangled) use case. All I 
had was an object and no way to xmlize it easily without JXTG, since 
such object lived (was instantiated) inside the flow. Eventually we 
found a workaround which resembles yours, but still I don't think that 
my situation was that much unusual...
