First of all thanks everyone for helping me out in this mailing list answering my questions that helped me a lot in getting through my GSoC. However, I am yet to complete my implementation. Therefore i will keep on pestering you with questions :)

Getting to the question,

We use the PAT to register permissions using the Permission Registration endpoint of the Protection API, do we have a standard way of associating the client who requests for access from the UMA protected resource server?

Thanks
