Extensions incorrectly reported as mandatory when constrained out of profile.

[dxh73]

A problem exists where an extension is being reported as included in an xml example structure when it is not included. For example:

Invalid Instance count for 'Patient.extension:registrationDetails' is 1, which is not within the specified cardinality of 0..0

XML example:

<Patient>
				<id value="dffd3330-dc21-11e7-9296-cec278b6b50a"/>
				<meta>
					<profile value="https://fhir.nhs.uk/STU3/StructureDefinition/CareConnect-EMS-PDS-Baby-Patient-1"/>
				</meta>
				<extension url="https://fhir.hl7.org.uk/STU3/StructureDefinition/Extension-CareConnect-EthnicCategory-1">
					<valueCodeableConcept>
						<coding>
							<system value="https://fhir.hl7.org.uk/STU3/CareConnect-EthnicCategory-1"/>

			</Patient>

The Patient.extension:registrationDetails extension is not in the example being validated. This extension is not mandatory (its profiled as 0..0).

If no extensions are included in an example, this error is not presented.

@dxh73: can you give me the profile https://fhir.nhs.uk/STU3/StructureDefinition/CareConnect-EMS-PDS-Baby-Patient-1. Without this profile I cannot reproduce the issue.

We are cleaning up old issues, and we noticed this issue was still open. Our apologies that it took so long that we gave a feedback on this issue.

Today I investigated the Patient instance above and did a validation against your profile (https://fhir.nhs.uk/STU3/StructureDefinition/CareConnect-EMS-PDS-Baby-Patient-1). It gave back an error about the Patient.Name. It lacks the use of official, which is correct, because the instance only has usual as use. Changing this use attribute to official the validator reports a success.

There is no errormessage anymore about the extensions, so I assume that has been solved. Therefor I close this issue.
