!!! Overview
[{$pagename}] Default requested [Authentication Context Class Values] is an [OAuth Dynamic Client Registration Metadata] entry. 

[{$pagename}] is a [JSONArray] of [strings] that specifies the default [acr] values that the [OpenID Connect Provider] is being requested to use for processing requests from this [OAuth Client], with the values appearing in order of preference. The [Authentication Context Class Reference] satisfied by the [authentication] performed is returned as the [acr] [Claim] Value in the issued [id_token]. 

The [acr] Claim is requested as a [Voluntary Claim] by this parameter. 

The [acr_values_supported] [OpenID Connect Discovery] element contains a list of the [acr_values_supported] supported by this server. 

Values specified in the [acr_values] request parameter or an individual [acr] [Claim] request override the [{$pagename}].
