Public trust/discovery services #11
Description
A generic problem with evolving ecosystems is maintaining interoperability without "freezing" specifications for extended periods of time.
Although my line of work is in payments, it is quite possible that identity/claims-consuming RPs also could benefit from being able to declare their capabilities and demands before the actual "transaction" takes place. This arrangement enables assertion producers to adapt assertions to the actual need of each RP. To make it scale, RPs would deploy .well-known URLs to trust/discovery services.
