These depedencies between items can easily being listed, but some dependencies are more hidden. For example another item can be referenced in an expression in a  [sdc-questionnaire-calculatedExpression](<http://hl7.org/fhir/uv/sdc/StructureDefinition/sdc-questionnaire-calculatedExpression>) extension. These dependencies are more hard to list without parsing the FHIR path expressions.\r\n\r\nThis extension lists all dependencies towards other items in this Questionnaire that are not explicitly used as a value in one of the parameters."
