Encounter resource (FHIR R4)

Encounter is a FHIR R4 resource. The Pidgeon engine generates synthetic Encounter instances and validates them against the R4 structure definitions.

Example

Validation context

• strict pidgeon validate grades a Encounter instance against the base R4 structure definition: missing required elements raise REQUIRED_FIELD_MISSING and cardinality violations raise CARDINALITY_MIN or CARDINALITY_MAX.(REQUIRED_FIELD_MISSING)
• strict Profile validation grades the same instance against an installed IG profile: profile cardinality findings carry FHIR-PROFILE-CARDINALITY and terminology binding findings carry FHIR-PROFILE-BINDING.(FHIR-PROFILE-CARDINALITY)
