Or, in general, one could include elements for both code Id and code
value, thereby supporting multiple codes. 

Also in general, process-specific schemas should probably be based on
what the process participants actually use. In this case, I think
there's a World Customs Organization in Brussels that could tell you
what is used for counter coding in international trade.
