	  for this example, we use a real URI, since this example does have a canonical URL
		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.

    properties (see, e.g. the valueset-example-supplement example)

    filter in the code system will need custom code to make it work.
    For this reason, filters are generally only defined in high value 
    published code systems (unlike this extremely low value example)
