## Known Issues

This table lists known issues with this specification at the time of publishing. We are working on solutions to these issues and encourage comments to help us develop these solutions.

Reference | Description
--- | ---
Example system URI | An inherited example system (e.g. `http://www.acme.com/identifiers/patient`) erroneously infers patient context. Implementers must use their own namespace URIs. The affected identifier profile is Endpoint (hcpd-EPI) - this profile includes the erroneous example `system` in their documentation.
Dependency on current version of Australian Provider Directory IG (FHIR IG) | The HCPD FHIR IG utilises Australian Service Interfaces and Australian Endpoint Payload Types from the Australian Provider Directory FHIR IG. However, including a dependency on v2.0.1 of the HL7 AU PD FHIR IG results in a publisher error due to a FHIR version mismatch: the AU PD IG is built on FHIR version 4.0.0 while HCPD requires version 4.0.1.
