sdc/unresolved-linkid

warning Reports a literal linkId that no item in the Questionnaire has.

What it checks

Looks at each where(linkId = '…') in a FHIRPath expression, and in each {{…}} fragment of an x-fhir-query, that selects items of this form: from %questionnaire, %resource or %context, from %qitem on an item, or from the expression’s own input, through item, answer, repeat(…), where(…) and select(…). The linkId must be the linkId of an item somewhere in the Questionnaire; whether the selection reaches that item’s depth is not checked.

Example

No item in this Questionnaire has linkId 'smokr'.
