[Openid-specs-ab] Attribute Exchange w/ OpenID Connect?

[Torsten Lodderstedt]

Hi,

in some cases we want to provide RPs with attributes but no user_id, 
which is similar to AX. How can this be realized in Connect? The scope 
value "openid" activates the OpenID mode at the AS but it also requests 
access to the user_id Claim. If we do not want to disclose a user_id, 
does this mean we need to define a new, distinct scope for our use case, 
e.g. "attribute_x"?

regards,
Torsten.
