So it boggles me to read there exists a statement about localization within the references for
title in the Error Objects, however there is no field for stating locale within error objects.
So here is a proposal for v1.1: Every
Error Object SHOULD contain a
locale member if the object is localized to a certain locale. This locale MUST follow the specification given by BCP47.
This proposal may extend to resource objects themselves, however that would better be left to the developer for obvious reasons.
