Validation context

strict pidgeon validate grades a Device 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)
