Thank you for moving this thing forward.
Here are my review comments.
Replace "I no appropriate" by "If no appropriate".
Replace "and indicated the URI" by "and indicates the URI".
Replace "by passing pass mobile network data" by "by passing mobile network data".
The terms IDP, OP and Authorization Server are used over the document and the message flow diagrams.
I think we should at least remove IDP because it seems to be no OpenID term.
Chapter 3.1.3 Error Response
I think we can copy at least error, error_description and error_uri from OAuth2 126.96.36.199 Error Response description.
Error codes may be invalid_request, unauthorized_client, access_denied, server_error, temporary_unavailable for regular errors. We should discuss if something like discovery_failed is sufficient or if we need to be more concrete.
The chapter for the issuer endpoint is also missing an error response section. I think we should use the same message format as in OAuth2 spec 5.2 without invalid_grant, unsupported_grant_type, invalid_scope but add invalid_code and discovery_failed.
I also think we should add msisdn as optional parameter to both, user interaction endpoint and issuer endpoint.
For the POST based flow because the app may already have the permission to query the msisdn from the device and then the user experience can be enhanced. See also Johns comment on https://bitbucket.org/openid/mobile/issues/6/general-questions
For the redirect based flow, because the RP may already know the msisdn and only wants a secure attestation for it. I know that mobile connect is aware of privacy and designed not to tell every RP the msisdn. But I'm sure that for some RPs this will become a valid use case and then the usability can be improved. The Discovery Service may deny the request if the client is not authorized to discover the mno by msisdn.
Over all, I think that the whole design will work :-)
I had no focus on the account chooser chapters, so no comments on that.
