Shearing files between programs without data loss

Several users have reported problems of data loss when passing files between programs. With XML and the Document Object Model, this will never happen, because it's easy for a programmer to work on the document tree, just adding nodes where additions have been made by user, and leaving the other parts unchanged. So a round-trip beetwen programs will be feasible, leading to a composite document having a common core of elements understood by both programs, some elements understood by program A only, and some by program B only.
