// Use proto3 syntax as an optimization. The difference is that proto2 stores
// unknown fields seen while decoding in an internal buffer (std::string) while
// proto3 completely drops them. Since during validation we only need to check
// for the presence of the trusted fields below, we can use proto3 as a way to
// speed up this process.

// 591673#17 for details.
