Validation Scope

fhir-zod focuses on structural FHIR validation.

Covered

• Field presence and cardinality
• FHIR primitive formatting
• Enum and code literal unions generated from the spec
• Choice-type exclusivity such as value[x]
• Selected constrained reference targets

Not covered

• Terminology validation
• FHIRPath execution
• Profile resolution
• Slicing
• FHIR server behavior
• End-to-end clinical or regulatory correctness

Practical implication

Use fhir-zod to validate the structural shape of data entering or leaving your system. If a workflow depends on terminology services, profile-aware validation, or server semantics, combine fhir-zod with other FHIR-specific tooling instead of stretching this package past its design target.

If you need the clinical or interoperability meaning of a resource, follow the version-specific HL7 links from FHIR Versions.
