Default values are not emitted by default. For enums, this is the first value which also must be = 0.

If you would like both MALE and FEMALE to be emitted, it’s recommended to use a nonsense zero value indicating it is either unknown or unset:

enum Sex{
  SEX_UNKNOWN = 0;
  MALE = 1;
  FEMALE = 2;
}
