public final class SchemaStage
extends Object

Validation stage SCHEMA (specification Section 14.2), as the reference runner implements it (conformance/run.py, stage_schema):

1. the strict reader of canonical-json-v1 (SCHEMA_INVALID_JSON, SCHEMA_DUPLICATE_KEY, SCHEMA_NON_INTEGER_NUMBER);
2. the version gates: a specVersion of another major.minor is VERSION_UNSUPPORTED_SPEC_VERSION; a header.registryVersion at or above the supported range is VERSION_REGISTRY_TOO_NEW;
3. the JSON Schema: a value outside an enum that names a registry group, and that the group does not list, is SCHEMA_UNKNOWN_CODE; any other schema error is SCHEMA_VIOLATION;
4. the array registry in strict mode: an unregistered array is SCHEMA_VIOLATION; a SET holding equal elements or a SEQUENCE with broken ordinals (SEMANTIC_ARRAY_KIND_VIOLATION) is deferred to stage SEMANTIC;
5. canonical order: a SET array out of its registered order is SCHEMA_NOT_CANONICAL.

The stage reports the findings of the first step that has any.
