<p class="MsoNormal"> PR #74: adds parameter for requesting credential type format<o:p></o:p></p>
<p class="MsoNormal"> Edmund said that they're still working on that one<o:p></o:p></p>
<p class="MsoNormal"> Kristina asked about convergence between Claims Aggregation and OIDC4VCI<o:p></o:p></p>
<p class="MsoNormal"> Edmund thinks they're going on the same direction<o:p></o:p></p>
<p class="MsoNormal"> Edmund mentioned possibly adding scopes<o:p></o:p></p>
<p class="MsoNormal"> Edmund will alert us when it's ready for working group reviews<o:p></o:p></p>
<p class="MsoNormal"> PR #57: Further specify how to use encrypted id_token_hint values<o:p></o:p></p>
<p class="MsoNormal"> Skipped because DW wasn't on the call at that point<o:p></o:p></p>
<p class="MsoNormal"> PR #131: fix: typo in 7.4.2. Status Response<o:p></o:p></p>
<p class="MsoNormal"> This fixes a syntax error. We should merge this.<o:p></o:p></p>
<p class="MsoNormal"> PR #134: Removing an option to submit a VC in the Authorization Request (#1443)<o:p></o:p></p>
<p class="MsoNormal"> Kristina reviewed discussions on binding VCs to participants, including p_nonce use and flaws with it<o:p></o:p></p>
<p class="MsoNormal"> She said that one option is embedding a presentation flow in an issuance flow<o:p></o:p></p>
<p class="MsoNormal"> But it's fairly complicated<o:p></o:p></p>
<p class="MsoNormal"> The alternative is something modelled on DPoP<o:p></o:p></p>
<p class="MsoNormal"> Mike would be interested in seeing a PR adding this<o:p></o:p></p>
<p class="MsoNormal"> PR #136: clarify holder binding<o:p></o:p></p>
<p class="MsoNormal"> Tobias wants the PR to focus on cryptographic holder binding<o:p></o:p></p>
<p class="MsoNormal"> He thinks that the subject binding could be out of scope<o:p></o:p></p>
<p class="MsoNormal"> Kristina said that the subject binding is important for smart health card use cases<o:p></o:p></p>
<p class="MsoNormal"> Possible implementation consideration on holder bindings<o:p></o:p></p>
<p class="MsoNormal"> There's no mechanism to detect replay<o:p></o:p></p>
<p class="MsoNormal"> Tobias and Jeremie said that sub_jwk is actually holder binding and not subject binding<o:p></o:p></p>
<p class="MsoNormal"> Nat has concerns about the term "holder" because in some jurisdictions, it represents the credential issuer<o:p></o:p></p>
<p class="MsoNormal"> Mike pointed out that we could reuse definitions from other specs, such as "holder" from the VC spec<o:p></o:p></p>
<p class="MsoNormal"> Kristina did add a "holder" definition in the PR, and requests reviews<o:p></o:p></p>
<p class="MsoNormal"> Nat asked if we possibly wanted to qualify the term "holder" with a prefix word<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Federation Specification<o:p></o:p></p>
<p class="MsoNormal"> Mike populated the IANA Considerations section<o:p></o:p></p>
<p class="MsoNormal"> We plan to publish a new draft after Roland harmonizes the IANA Considerations section with the rest of the specification<o:p></o:p></p>

<p class="MsoNormal"> #1450: [oidc4vci] Proposal: Move custom presentation exchange logic to a different spec<o:p></o:p></p>
<p class="MsoNormal"> Jeremie and Kristina believe that the input VP logic in the authorization request has been removed<o:p></o:p></p>
<p class="MsoNormal"> Kristina is working on an alternative<o:p></o:p></p>
<p class="MsoNormal"> Jeremie said that when PR #134 is merged, we can close this<o:p></o:p></p>
<p class="MsoNormal"> Jeremie says that we're doing a presentation exchange that's part of an issuance flow<o:p></o:p></p>
<p class="MsoNormal"> He thinks that some of this should be part of the OIDC4VP spec<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Next Call<o:p></o:p></p>
<p class="MsoNormal"> The next call will be a regular working group call on Thursday, March 17, 2022 at 7am Pacific Time, followed by a SIOP call<o:p></o:p></p>
