In the developer doc: https://developers.google.com/protocol-buffers/docs/proto3#custom_options, it mentions the following:
Protocol Buffers also allows you to define and use your own options. This is an *advanced feature* which most people don't need. If you do think you need to create your own options, see the Proto2 Language Guide <https://developers.google.com/protocol-buffers/docs/proto#customoptions> for details. Note that creating custom options uses extensions <https://developers.google.com/protocol-buffers/docs/proto#extensions>, which are permitted only for custom options in *proto3.* Should the last word "proto3" be "proto2"?
