I think I know what you mean. Well, yes, the point seems to be, that
order may or may not matter and that if it does not, the tools sometimes
reorder needlessly (because they convert it there and back to some other
representation that does not keep the ordering). So the trick is to let
the merge tool know, where the order matters. If the XML schema spec was
good, it would tell this, but I don't really believe it is as good.
