DCQL pattern: claim VALUE matching - accept a credential only when a claim equals one of an allowed list, using the values array on a claim query in OpenID4VP on the iGrant.io Organisation Wallet Suite. Example: a delivery service accepts a PID/address credential (dc+sd-jwt) only for postal codes inside its delivery zones. Geographic or attribute-gated eligibility checks with EUDI Wallet (EUDIW) under eIDAS 2.0.
