I'm coming more and more to the opinion that the only semantics which matter in the end are the semantics seen by the recipient of the message. There may be times when prior sender-recipient communications have more or less established those, and there are lots of times when the recipient wants to make the sender happy (typically $$$$ at stake), but I don't think there's anything fundamental about XML, XML Schema, or any other related technology which counters that case. Schemas are really useful for a wide variety of processing, but I'd strongly encourage people to treat them as an aid to processing rather than a magic wand for establishing communications.
