Hi Sascha,

The change you found in the draft 04 is the change made to the JAR (JWT
Secured Authorization Request). Now, "client_id" is mandatory. I summarized
technical details about JAR in the article below. It describes the reasons
for the necessity of "client_id". PAR is mentioned there, too.

Implementer's note about JAR (JWT Secured Authorization Request)

Best Regards,
Taka
