code: func ParseSchema(rawSchema string) (Schema, error) {
  	return ParseSchemaWithRegistry(rawSchema, make(map[string]Schema))
  }
docs: // ParseSchema parses a given schema without provided schemas to reuse.
  // Equivalent to call ParseSchemaWithResistry(rawSchema, make(map[string]Schema))
  // May return an error if schema is not parsable or has insufficient information about any type.
