SystemCodeDisplayDefinition
http://hl7.org/fhir/questionnaire-enable-operator   exists Exists True if the determination of 'whether an answer exists for the question' is equal to the enableWhen answer (which must be a boolean).
http://hl7.org/fhir/questionnaire-enable-operator   = Equals True if at least one answer has a value that is equal to the enableWhen answer.
http://hl7.org/fhir/questionnaire-enable-operator   != Not Equals True if no answer has a value that is equal to the enableWhen answer.
http://hl7.org/fhir/questionnaire-enable-operator   > Greater Than True if at least one answer has a value that is greater than the enableWhen answer.
http://hl7.org/fhir/questionnaire-enable-operator   < Less Than True if at least one answer has a value that is less than the enableWhen answer.
http://hl7.org/fhir/questionnaire-enable-operator   >= Greater or Equals True if at least one answer has a value that is greater or equal to the enableWhen answer.
http://hl7.org/fhir/questionnaire-enable-operator   <= Less or Equals True if at least one answer has a value that is less or equal to the enableWhen answer.

Explanation of the columns that may appear on this page:

Lvl A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
