040 * The value set system has a collection of value sets that define code systems,
041 * and construct value sets from them
042 * 
043 * Large external terminologies - LOINC, Snomed, etc - are too big, and trying
044 * to represent their definition as a native value set is too large. (e.g. LOINC
045 * + properties ~ 500MB). So we don't try. Instead. we assume that there's some
046 * external server that provides these services, using this interface
047 * 
048 * The FHIR build tool uses http://fhir.healthintersections.com.au for these
049 * services
