How to translate the param field?

[cncal]

Package version:

v10

Enhancement:

Is it possible to translate the param field?

Code sample:

package main

import (
	"fmt"
	"reflect"

	"github.com/go-playground/locales/en"
	ut "github.com/go-playground/universal-translator"
	"github.com/go-playground/validator/v10"
	en_translations "github.com/go-playground/validator/v10/translations/en"
)

var (
	uni      *ut.UniversalTranslator
	validate *validator.Validate
)

func main() {
	en := en.New()
	uni = ut.New(en, en)
	trans, _ := uni.GetTranslator("en")

	validate = validator.New()
	en_translations.RegisterDefaultTranslations(validate, trans)

	validate.RegisterTagNameFunc(func(field reflect.StructField) string {
		locale := field.Tag.Get(`json`)
		if locale == `` || locale == `-` {
			return ``
		}
		return locale
	})

	type Num struct {
		Num1 uint8 `json:"num1"`
		Num2 uint8 `validate:"gtfield=Num1" json:"num2"`
	}

	num := Num{
		Num1: 0,
		Num2: 0,
	}

	err := validate.Struct(num)
	if err != nil {
		errs := err.(validator.ValidationErrors)
		for _, e := range errs {
			// can translate each error one at a time.
			fmt.Println(e.Translate(trans))
		}
	}
}

What did I expect to see?

num2 must be greater than num1

What did I see instead

num2 must be greater than Num1

tips: num1 is the tag value of struct field Num1

+1, we definitely need this feature, its very important to be able to register
RegisterParamNameFunc or something, similar to the
RegisterTagNameFunc

Hi, I wonder when the solution will be in production. Or if there is a way to implement it in my project temporarily. Thanks!
