<!– 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)
