       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.<br>        Related to <a href="https://github.com/openid/OpenID4VCI/issues/91" target="_blank">https://github.com/openid/OpenID4VCI/issues/91</a><br><br>We agreed to cancel next week's DCP WG meeting due to IETF 118.</div>
