David agrees that it should be defined in the ecosystems scope, in this case the EU - it should re-use the existing mechanism like DCQL. Christian adds that one of the big questions is what exactly a Wallet Attestation looks like - if it is only a link to a certification or holds those claims itself. Torsten mentions that we are back to the starting point of the discussion and wonders how to proceed the discussion. Paul states that his conclusion from the hybrid call was that there is benefit in having a common format defined. Lee adds that it is a special wallet and will create UX issues unless there is some special treatment and might also have privacy problems. In that sense, it is a special type of request. Hicham states that issuance and presentment have really different assumptions and at presentments we have to be a lot more careful.
