But if we do this, what happens (as David >Carlisle mentioned) to processing code that uses fully-qualified names (such >as code that uses XPath expressions)? If we use namespaces for versioning, should there be a separate RDDL document per version? Or should there be a RDDL document containing information on multiple versions and some kind of identifier (an XPath? an ID used in the namespace URI?) that can identify which version applies to a given document?
