The bug

In the Advance Care Planning composition profile (composition-acp-1), the invariants on the following 2 extensions have faulty FHIRPath expressions, related to the use of 'conformsTo'. The consequence of which is that acceptable content for these elements always fails to be valid against these invariants.

1) Element: Composition.extension:compositionAuthorRole

• key: inv-dh-cmp-04
• Description: A practitioner role shall conform to PractitionerRole with Practitioner with Mandatory Identifier
• FHIRpath expression: Composition.extension('http://hl7.org.au/fhir/StructureDefinition/composition-author-role').resolve().conformsTo('http://ns.electronichealth.net.au/ci/fhir/3.0/StructureDefinition/practitioner-ident-1')

  2) Element: Composition.attester.extension:attesterRelatedParty

• key: inv-dh-cmp-05
• Description: A related party shall conform to RelatedPerson with Mandatory Identifier
• FHIRpath expression: Composition.attester.extension('http://hl7.org.au/fhir/StructureDefinition/attester-related-party').resolve().conformsTo('http://ns.electronichealth.net.au/ci/fhir/3.0/StructureDefinition/relatedperson-ident-1') |

What I expected to happen

Acceptable content for this element shall be valid against these invariants. Unacceptable content for this element shall not be valid against these invariants.

The fix

The correct (and simplified) FHIRPath is (respectively):

valueReference.reference.resolve().conformsTo('http://ns.electronichealth.net.au/ci/fhir/3.0/StructureDefinition/practitioner-ident-1')
valueReference.reference.resolve().conformsTo('http://ns.electronichealth.net.au/ci/fhir/3.0/StructureDefinition/relatedperson-ident-1')

[SatyaYelisetti]

Work is in progress to check if that invariants have relative FHIRPath.

[SatyaYelisetti]

The invariants have now been changed to have relative paths and are now under review.

Changes to the FHIRpath can now be found in the above commit of the structure definition.
