  <!--    
    Observations are often coded in multiple code systems.
      - LOINC provides a very specific code (though not usefully more specific in this
   particular case)

      - LOINC provides codes of varying granularity (though not usefully more specific
   in this particular case) and more generic LOINCs  can be mapped to more specific codes
   as shown here

      - snomed provides a clinically relevant code that is usually less granular than
   LOINC
      - the source system provides its own code, which may be less or more granular than
   LOINC

  <!--     In FHIR, units may be represented twice. Once in the
    agreed human representation, and once in a coded form.
    Both is best, since it's not always possible to infer
    one from the other in code.

    When a computable unit is provided, UCUM (http://unitsofmeasure.org)
    is always preferred, but it doesn't provide notional units (such as
    "tablet"), etc. For these, something else is required (e.g. SNOMED CT)
