How it works

Draft-07 style keywords are supported: type, required, properties, items, enum, const, minimum/maximum, minLength/maxLength, pattern, uniqueItems and additionalProperties.
Combinators anyOf, allOf, oneOf and not are evaluated, and local $refs such as #/definitions/name are resolved.
Each error reports the instance path, the keyword that failed and what was expected.
