[Openid-specs-ab] display_identifier handling in OpenID 2.0 to OpenID Connect Migration

[nov matake]

OpenID 2.0 has 2 identifier, openid.claimed_id & openid.identity.
For historically reasons, some libraries/RPs are using openid.identity as user identifier, unfortunately.

Does this migration spec have plan to returning openid.identity? or just ignore such buggy libraries/RPs?

The biggest issue would be Y! inc & Y! Japan’s case.
They have fragment component only in openid.claimed_id.
