    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
    &quot;tablet&quot;), etc. For these, something else is required (e.g. Snomed-CT)
