FHIR Infrastructure Work Group

Trial Use

Use Context: Any

Official URL: `http://hl7.org/fhir/StructureDefinition/questionnaire-maxOccurs`				Version: 5.0.0-snapshot3
draft as of 2013-07-04				Computable Name: QMaxOccurs
Flags: Non-Modifier				OID: 2.16.840.1.113883.4.642.5.1235

Context of Use: Use on Element ID Questionnaire.item or Element ID ElementDefinition, with Context Invariant = type!='display' and (repeats=true or %extension.valueInteger=1)

Definition

The maximum number of times the group must appear, or the maximum number of answers for a question - when greater than 1 and not unlimited.

Comment:

Only relevant if the element has repeats=true and there's a need to constrain the number of allowed repetitions. See additional guidance and examples in the SDC implementation guide.
