Serialization of XDM

Someone needs to sit down and write down the requirements and use cases.

One requirement that someone suggested was of the nature of "lossless
round-tripping". That would imply that given a sequence (N, M), not only
does (N is M) retain its value after serialization and parsing, but so does
(N/.. is M/..): which means you can't just serialize the subtrees rooted at
the nodes in the sequence, you have to serialize the entire document in
which these nodes are contained.

Perhaps this explains why there is currently no standard in this area.
