ObjectSchemaBuilder

Provides the universal and metadata methods ($id, title, description, enum, const, anyOf, allOf, oneOf, not, if, errorMessage, extend, build, …) plus the object-specific constraints below. Per type locking, only this type’s constraints are accessible once the builder is locked to object.
