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