<!--     
    for this example, we use a real URI, since this example does have a canonical address
    at which it's posted. Alternatively, We could have used an OID, or a UUID 

    note that since we give a literal URL here, there's an expectation 
      that accessing that URL will give some form of representation of 
      the full code system, or a pointer about how to get more infomration. 
  
      This is not an absolute requirement, but it may be enforced by some 
      servers - for instance, the HL7 valueset registry will.     -->

    system, not the version, if existing codes are redefined (e.g. don't do that!)    -->
