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