!!! Overview
[{$pagename}] is a [Discovery Mechanism] which specifies a way to normalize a user identifier to derive a resource and especially a host for [OpenID Connect Discovery].

While the [OpenID Connect Discovery] works well for identifiers as email addresses and [URLs], it does not work for typical identifiers from the [Mobile Network Operators] space.  When in a mobile environment, and using [Mobile Device], [MSISDN]'s or [IP Address]es are typical resources identifying a user or the respective [Mobile Network Operator] ([MNO]).

The structure of those identifiers does not allow for an algorithmic normalization. Thus it will be necessary to have a specific service to perform the normalization.

[{$pagename}] specifies the interface of this service.  Part of the interface specification will be the identification of possible user input identifier types relevant in the [Mobile Connect] scenario.  

Remark: Some of those user input identifier types may not identify a single user/device but may be sufficient to identify the right [Mobile Network Operator].  An [example] for this is the [MNC]/[MCC] tuple (mobile network code/ mobile country code) or the IP address range.

[{$pagename}] also specifies how a client registers with the [MNO] discovery service and how [Account Chooser] service [Account Chooser] can be used to further improve user experience in the overall [OpenID Connect MODRNA Authentication Profile 1.0].
