  TEST_ENUM_UNSPECIFIED = 0;
  TEST_ENUM_ONE = 1;

  TEST_ENUM_THREE = 3;
  TEST_ENUM_FOUR = 4;
  TEST_ENUM_FIVE = 5;
}

message TestMap {
  optional string key = 1;
  optional string value = 2;
}

  optional string nested_string = 1;
  optional int32 nested_int = 2;

  optional int32 nested_required_int = 5 [(validate_required)=true];
  optional bool nested_required_bool = 6 [(validate_required)=true];
  optional TestEnum nested_enum = 7;
  repeated TestEnum nested_repeated_enum = 8;
  optional TestMap map = 9 [(json_map)=true];
