<!–

        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 information. 

                      This is not an absolute requirement, but it may be enforced by some 
                      servers - for instance, the HL7 valueset registry will.    -->
<url value="http://hl7.org/fhir/CodeSystem/example"/>

<!– an imaginary identifier. This is a non FHIR identifier - might be used in a

        v2 context (though you always need to translate namespaces for v2)    -->
<identifier>
  <system value="http://acme.com/identifiers/codesystems"/>
  <value value="internal-cholesterol-inl"/>
</identifier>

<!– for version, we are going to simply use the day of publication. This is also

  arbitrary - whatever is here is what people use to refer to the version. 
  Could also be a UUID too. Note that you should change the identify of the code 
  system, not the version, if existing codes are redefined (e.g. don't do that!)   -->
