use omitempty in json tag , instead of required tag?

[podhmo]

type Ob struct {
    Name   string `json:"name"` // required
    Age    int    `json:"age,omitempty"`
    Parent *Ob    `json:"parent"`

    Nickname int  `json:"nickname,omitempty" required:"true"` // required
    Status   bool `json:"status" required:"false"`
}
