  "description" : "Reusable value set for binary (Yes/No/Unknown) responses on the\nWHO MCCoD Frame B questions. Used consistently across all Frame B\nObservations that carry a Yes/No/Unknown answer.\n\n- Yes → HL7 v2-0136 #Y\n- No  → HL7 v2-0136 #N\n- Unknown → data-absent-reason #asked-unknown\n  (the question was asked but the answer is not known)\n\nThis pattern follows standard FHIR practice for representing\nunknown responses without creating unnecessary local code systems.",
