Pull Requests
    The following PRs were merged:
        https://github.com/openid/OpenID4VCI/pull/65 (add identifiers for
issuing credential of the same type, different content).
        https://github.com/openid/OpenID4VCI/pull/64 (clarify credential
error response can be authorization or credential request error).

    https://github.com/openid/OpenID4VCI/pull/66 (add data integrity
verifiable presentation as proof of possession).
        Is almost good to be merged, with some changes required by Kristina.

    https://github.com/openid/OpenID4VCI/pull/70 (Wallet notifying the
Issuer of acceptance/rejection of issued credential).
        Needs more reviews.

    https://github.com/openid/OpenID4VCI/pull/78 (make
authorization_servers credential issuer metadata parameter an array).
        Pedro will also take a look at it. Will be merged if nothing major
is found within a week.

    https://github.com/openid/OpenID4VCI/pull/86 (credentials Credentials
Offer parameter values identifying credentials_supported object(s) in the
issuer's metadata).
        Pedro will review it.

    https://github.com/openid/OpenID4VCI/pull/95 (add user_pin_length and
user_pin_description to Credential Offer).
        Pedro will review it.

Issues
    https://github.com/openid/OpenID4VCI/issues/97 (Uniform usage of "JSON
String" vs. "String" (/Object/Array/...) ).
        Mostly editorial. The goal is to avoid the "JSON" prefix when not
needed.
        Daniel to create PR.

    https://github.com/openid/OpenID4VCI/issues/91 (Naming of
credential_supported / credential / credential_instance)
        Paul and Daniel presented the reasoning behind it.
        Issue to be discussed next week, probably in front of a whiteboard
at IETF 118.

    https://github.com/openid/OpenID4VCI/issues/96 (User PIN is not a PIN)
        Common agreement that PIN (Personal Identification Number) is not a
good fit.
        Leave it open until next week ("bikeshedding for a week").

    https://github.com/openid/OpenID4VCI/issues/93 (How are credential
copies issued?)
        It seems the main question in this issue is how to determine how
many "copies" of a credential should be issued. Is that determined by the
wallet or by the issuer.
        Related to https://github.com/openid/OpenID4VCI/issues/91

We agreed to cancel next week's DCP WG meeting due to IETF 118.
