Mark: There are no actual usage guidelines, however I recommended using "fixed" value attributes on a schema or DTD rather than use Namespaces. This would cut down on th eactual size and processing overhead of the business payloads unless someone decided to do a validating parse. An unvalidated parse would simple ignore the [ DTD | schema ] and process the message. The UID's would be used mainly for retreiving semantic meaning in order to map from one message to another.
