Observations are often coded in multiple code systems.
- 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

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)

examples are correct and useful, but they are not a normative part
of the specification.
