To my understanding, the proposal is the following:

A registration can be done without the "ep" query parameter, iff the Endpoint Client Name can be derived in another way from the registration message. This way should (or I guess Hannes would say MUST) be the security context. In that sense, "ep" as registration query parameter becomes optional, but "ep" remains a central, mandatory attribute in the RD for each registered resource (used for endpoint lookup, filtering etc.).


Thanks Ludwig for your pointer how this could work.

@Hannes: Could you provide some more detail, how exactly the Endpoint Client Name is extracted from "security context"? Overall, I like this, but we should provide concrete text on how people should do it.

Best,
Matthias
