# Discussion about Timeline for standard publication<br>
- Marjin thinks new query language should go in before 1.0<br>
- Lee asks whether it makes sense to wait with 1.0 for longer time
and get into the next implementing act round<br>
- Joseph responds that we already missed first round of eIDAS
implementing acts and aim for second round, fear of missing out,
but there might be even a third<br>
- situation is that 1.0 feels like a step in the door and waiting
for too long may be too much of a gamble<br>
- Lee agrees but also sees the risk that we get stuck with PE<br>
- Joseph says that we will have PE probably anyway through ISO mDL<br>
- people ask how much effort needs to be done for squeezing new
query language in<br>
- Mike points out there are substantial open points and we need
implementations<br>
- Joseph asks if anybody objects trying to get new query language
into 1.0<br>
- Daniel will provide summary and update on Thursday call<br>
<br>
# How can verifiers that support multiple trust models/ecosystems
know how to authenticate to the wallet? <br>
- <a class="moz-txt-link-freetext" href="https://github.com/openid/OpenID4VP/issues/248">https://github.com/openid/OpenID4VP/issues/248</a><br>
- Verifier doesn't know with which certificate to sign the request<br>
- allow multiple signatures?<br>
- John points out this architecture is nuts, instead Wallet should
figure out that Verifier is correct to his trust model, e.g. with
trust marks<br>
- different issuers will have different RP policies<br>
- Lee thinks RP shouldn't care about the Wallet at that point but
about the issuers<br>
- Daniel thinks RP is talking to ecosystems<br>
- Brian points back to the issue, in the context of BrowserAPI
already has requests parameter to allow this instead of using JWS
json serialization<br>
- Christian says we need embedded issuer policies (in credential
itself or metadata) to cleanly solve this<br>
- Martjin thinks in the long run solutions may unite and may not
need it, but in the short run complications may be expected,
allowing multiple RP certificates may smooth this<br>
- John: we probably need to do it and fix it later "if it falls
over", hinting to OpenID Federation<br>
- Daniel explains the suggestion, that reuses JWS JSON
Serialization<br>
<br>
# Deferred endpoint fixing it?<br>
- there seem to be some issues with Deferred Issuance flow<br>
- if you are aware of any problems please report!<br>
<br>
# Define claims display description and claims path query -
<a class="moz-txt-link-freetext" href="https://github.com/openid/OpenID4VCI/pull/276">https://github.com/openid/OpenID4VCI/pull/276</a><br>
- there is a bug in metadata that would need to be fixed<br>
- please provide Feedback!<br>
<br>
# Permit the use of the new query language instead of presentation
exchange. <a class="moz-txt-link-freetext" href="https://github.com/openid/OpenID4VP/issues/255">https://github.com/openid/OpenID4VP/issues/255</a><br>
- small issue that enables the new query language without a
breaking change<br>
- we need PR!<br>
<br>
c_nonce PR: Are we going to mandate support of nonce endpoint for
issuers that require nonces?
<a class="moz-txt-link-freetext" href="https://github.com/openid/OpenID4VCI/pull/381#pullrequestreview-2292605172">https://github.com/openid/OpenID4VCI/pull/381#pullrequestreview-2292605172</a><br>
- this removes c_nonce from token endpoint and introduces a new
nonce endpoint instead<br>
- we need more feedback on this!<br>
<br>
client_id_scheme security (
<a class="moz-txt-link-freetext" href="https://github.com/openid/OpenID4VP/issues/124">https://github.com/openid/OpenID4VP/issues/124</a> )<br>

<a class="moz-txt-link-freetext" href="https://github.com/openid/OpenID4VCI/issues/386">https://github.com/openid/OpenID4VCI/issues/386</a><br>
- add extensiability to Credential Response, e.g. for ARKG handles
in the future<br>
- three options are provided<br>
- Option#2 with breaking change, but currently favored.<br>
- please provide feedback!<br>
<br>
Key attestation first draft PR - please review:
