AU Base Patient - add better contact.relationship binding

[robeastwood-agency]

The AU Base Patient profile does not constrain the base resource binding on Patient.contact.relationship from the default extensible binding of Patient Contact Relationship. The default v2-0131 codesystem is missing some options that would be useful to represent; such as

• carer
• nominated representative
• guardian

To support these additional concepts, the NCTS has developed (and published) a valueset that extends the values in the above v2-0131 codesystem. See https://healthterminologies.gov.au/fhir/ValueSet/contact-relationship-type-1

Looking to have this considered for inclusion in the AU Base Patient profile.

The additional concepts (from SNOMED CT) are:

• 133932002: Carer
• 1072531000168103: Nominated representative
• 394619001: Guardian
• 1155871000168103: Kinship carer

Discussed in PA WG: Create a new valueset including v2-0131 + contact-relationship-type-1 and reference in AU Base Patient profile with extensible binding. Will progress.

Note that contact-relationship-1 is already a value set that includes v2-0131 + the additional codes, i.e. it is defined as:
