Generated Narrative: CodeSystem questionnaire-enable-operator

This case-sensitive code system http://hl7.org/fhir/questionnaire-enable-operator defines the following codes:

Code	Display	Definition
exists	Exists	True if whether an answer exists is equal to the enableWhen answer (which must be a boolean).
=	Equals	True if whether at least one answer has a value that is equal to the enableWhen answer.
!=	Not Equals	True if whether at least no answer has a value that is equal to the enableWhen answer.
>	Greater Than	True if whether at least no answer has a value that is greater than the enableWhen answer.
<	Less Than	True if whether at least no answer has a value that is less than the enableWhen answer.
>=	Greater or Equals	True if whether at least no answer has a value that is greater or equal to the enableWhen answer.
<=	Less or Equals	True if whether at least no answer has a value that is less or equal to the enableWhen answer.
