Explicit Endpoint

Research such as the ISO BASIN Document points out that it is a good practice to explicitly state the intended interaction endpoints and the message position in the sequence in a tamper evident manner so that the intent of the initiator is unambiguous.

Further, if dynamic discovery ([OAuth 2.0 Authorization Server Metadata]]) is used, then the metadata related endpoints also come into question.

In RFC 6749, while Redirection URI is included, others are not included in the Authorization Request. As the result, the same applies to Authorization Request Object.

The lack of the link among those endpoints are sited as the cause of Cross-Phase Attacks introduced in FETT. An extension specification should be created as a measure to address the risk.
