6.13.2.18.4 Rules & constraints

• Per-result typed fields selected by the profile's ObservationType.qualifier_schema.
• Only fields/cardinalities listed by the family profile in the canonical type catalog are accepted; no ad-hoc source column names.
• qualifier_schema code/version identifies that exact closed schema; the family name is not itself a per-record qualifier.
• Does not override matrix, analyte, canonical unit or denominator fixed by PropertyDefinition.
• Method, time, anatomical site, sample, source and aggregation are common fields, not duplicated qualifiers.
