DCQL query template for the Payment Account Credential (TS12) from the iGrant.io verifiable data registry. The dc+sd-jwt query asks for iban, bic and currency, and the vct is the payment_account VCT metadata URL of the issuer. Use this skill when you build a Strong Customer Authentication (SCA) flow under ETSI TS 119 462 (TS12): the presentation definition must set a transactionDataDefinitionType, and the send request must carry the matching transactionData.
