Hi Vladimir

We've only prototyped the code around the RP-initiated logout spec text, 
hence the question, in this flow, it is actually the RP-controlled 
endpoint that has the user being redirected to it, once OIDC completes 
this RP-initiated logout request, and this RP endpoint will display the 
So is it something that it is not that OIDC can control, which Locale to 
use ?
I may've missed something with respect to how this flow actually works 

Thanks, Sergey

For instance, the value "fr-CA fr en" represents a preference for French as spoken in Canada, then French (without a region designation), followed by English (without a region designation). An error SHOULD NOT result if some or all of the requested locales are not supported by the OpenID Provider.
