// or if you prefer you can use the Flatten function
// NOTE: I find this usefull when using a more hard static approach of checking field errors.
// The above, is best for passing to some generic code to say parse the errors. i.e. I pass errs
// to a routine which loops through the errors, creates and translates the error message into the
// users locale and returns a map of map[string]string // field and error which I then use
// within the HTML rendering.
flat := errs.Flatten()
fmt.Println(flat) // output: map[Age:Field validation for "Age" failed on the "lte" tag Addresses[0].Address.City:Field validation for "City" failed on the "required" tag]

fmt.Println(err.Value) // output:
// from here you can create your own error messages in whatever language you wish
