Subject: [Openid-specs-digital-credentials-protocols] DCQL as the only query language in OpenID4VP Final 1.0

Hi All,

Here is a short note that after multiple discussions in the WG (issue #211<https://github.com/openid/OpenID4VP/issues/211>), and based on the implementation feedback, WG has made a decision to remove Presentation Exchange from Final 1.0 specification to improve interoperability and avoid fragmentation in the market.

A PR #479<https://github.com/openid/OpenID4VP/pull/479> that removes PE has been filed and is on track to be merged in 2 days.
Please respond to this note if there are any concerns. You can also bring them to the DCP WG call tomorrow.

Also a reminder that First Implementer's draft of HAIP already mandates DCQL as the only query language for both vanilla OpenID4VP and OpenID4VP over Digital Credentials API.

Best,
DCP WG co-chairs
