Information | StructureDefinition.date | Values for date differ: '2024-12-11T18:49:53+00:00' vs '2026-03-26T15:54:25+00:00'
Information | VisionPrescription.language | Example/preferred bindings differ at VisionPrescription.language using binding from CRDVisionPrescription
Information | StructureDefinition.comment | Values for comment differ: 'This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.' vs 'Any references found in this resource, with the exception of 'Patient' could potentially be resource-specific and thus transmitted as contained resources.'
Warning | VisionPrescription.contained | Elements differ in definition for mustSupport: 'false' vs 'true'
Information | StructureDefinition.short | Values for short differ: 'Additional content defined by implementations' vs 'Extension'
Information | StructureDefinition.definition | Values for definition differ: 'May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.' vs 'An Extension'
