Some resources return internationalized data. In those case, the seller can use the locale parameter:
Example: get assessments information in english (US)
Locale format is <ISO-639>_<ISO-3166> (eg "en_US"). 2-letters locales (e.g. "en") will not be accepted.
When a locale is returned in a response, it also uses this format.
Accepted locales are the ones corresponding to the languages that have been activated by the operator in the back-office.
