Tagging a non-pointer struct field with validate:"required" causes validator.New().Struct() to reject an uninitialized zero-value struct.

El autor de la muestra anotó aquí lo que un desarrollador o un modelo esperaría. El contrato de abajo es lo que realmente se ejecutó.

validator.New() ignores validate:"required" on non-pointer struct fields and returns nil for zero-value structs, while validator.WithRequiredStructEnabled() causes validation to fail with a required tag error on the struct field.
Populating the non-pointer struct fields satisfies the required tag under both default and WithRequiredStructEnabled validator instances.
Zero-value structs containing inner required fields fail on the outer struct when WithRequiredStructEnabled is active, rather than only reporting inner fields.
