user_id,
// 使用 password 这个规则，验证 req.body.oldPwd 的值
old_password: password,
// 使用 joi.not(joi.ref('oldPwd')).concat(password) 规则，验证 req.body.newPwd 的值
// 解读：
// 1. joi.ref('oldPwd') 表示 newPwd 的值必须和 oldPwd 的值保持一致
// 2. joi.not(joi.ref('oldPwd')) 表示 newPwd 的值不能等于 oldPwd 的值
// 3. .concat() 用于合并 joi.not(joi.ref('oldPwd')) 和 password 这两条验证规则
password: joi.not(joi.ref('old_password')).concat(password),
repassword: joi.ref('password')

How does joi.ref work?

joi.ref is a method in the Joi validation library that allows you to reference other keys in the schema or the parent object and use their values for validation purposes. It returns a reference object that can be used as a schema property value. When the schema is validated, the value of the referenced key is retrieved and used to validate the current property.

const Joi = require("joi");

const schema = Joi.object({
  password: Joi.string().min(8).required(),
  passwordConfirmation: Joi.string().valid(Joi.ref("password")).required(),
});

const data = {
  password: "password123",
  passwordConfirmation: "password123",
};

const { error, value } = schema.validate(data);
if (error) {
  console.log(error.message);
} else {
  console.log(value);
}

In this example, Joi.ref('password') is used to ensure that the value of passwordConfirmation matches the value of password. If they don't match, a validation error is thrown.

~~~~~~~~~~~~~~~~


(!) O trecho pointSchema.invalid(Joi.ref('startingAddress')) que utiliza as validações já definidas em pointSchema e acrescenta
uma nova validação, através da função Joi.ref(), para comparar o valor deste atributo com o atributo startingAddress e se forem
iguais o schema retorna uma mensagem de erro que informa que o valor do atributo endingAddress é inválido.

Note that references can only be used where explicitly supported such as in `valid()` or `invalid()` rules. If upwards
(parents) references are needed, use [`object.assert()`](#objectassertref-schema-message).

```js
const schema = Joi.object().keys({
    a: Joi.ref('b.c'),
    b: {
        c: Joi.any()
