Hmmm... good question.  I'm not entirely sure.  At the very least, I'd say 
the round-trip should be idempotent.

I'm not particularly in favour of a parser adding to a model (I distinguish 
here between "adding to" and "annotation" in that I don't think 
"annotations" would appear in a re-serialization, but rather would be used 
to reconstrict the original serialized form faithfully).
