Get top level struct field when nested error occurred.

[nojaf]

Hello,

I'm facing the following situation:

type Child struct {
	Name string `validate:"max=5"`
}

type Parent struct {
	Children []Child `validate:"dive"`
}

func TestDive(t *testing.T) {
	parent := Parent{
		Children: []Child{
			{
				Name: "valid",
			},
			{
				Name: "invalid",
			},
		},
	}

	v := validator.New()

	err := v.Struct(parent)

	if err == nil {
		t.Error("Expected error, got none")
	}
}

Validation failed for a field of Child inside the Children slice.
But in my case, I would need to know that Children failed for the top-level struct.
Is there any way I can access that information? I would need to serialize the entire Children slice to remain compatible with another validation framework.
