      - WG agrees to merge PR, issues opened for remaining gaps related to
      AnonCreds and W3C VCs
      - Issues


   - Issue 24 - privacy considerations
   <https://github.com/openid/OpenID4VP/issues/24>
      - Ready for PR, requirements in comments
      - Brian going to take a first shot, Torsten and Nat can help


   - PR 466 - rename client id prefixes
   <https://github.com/openid/OpenID4VP/pull/466>
      - A lot of approvals, small breaking change
      - Christian had a small remark that naming should be updated in HAIP
      and other specs (Christian to pick this up)
      - Aaron resolved merge conflicts, so it's mergeable


   - Issue 299 - iss value to be used in signed requests is not clear?
   <https://github.com/openid/OpenID4VP/issues/299>
      - Ready for PR
      - WG agrees: verifier may include it, wallet must ignore it
      - Christian to create PR before next monday


   - Issue 289 - DCQL Define details for the purpose property
   <https://github.com/openid/OpenID4VP/issues/289>
      - Some contradicting views on the issue
      - Main concern is that there's concerns with allowing verifiers to
      render free-form text strings in a trust-elevated part of the Wallet UI.
      - See the WG discussion comment from Kristina on the issue for more
      details
      - No agreement during working, at least one strong objection against
      removing the purpose for 1.0

OpenID Connect WG discussion

   - PR 468 - slight tweak to default treatment of https URLS
   <https://github.com/openid/OpenID4VP/pull/468>
      - Shortly discussed a new proposal from the OpenID Connect WG
      discussion
      - Proposal from Aaron which multiple people support, but also
      objection(s)
