Recommendation for gettext?

[peaceful-james]

What is the recommended way to translate the validation error messages?
Maybe it would be good to add this to the repo? I can work on a PR if it is needed.

There is no recommended way here.

In the codebase in which I was using ExPhoneNumber most extensively there is a wrapper/utility module (Utilities.Phone) which outputs as errors :invalid_country_code or :invalid_phone_number and then higher up the line those are output as translated user friendly text. And this was sufficient.

Having a tutorial how to handle the translations problem could be helpful.
