-This specification includes both required and optional fields. An issuer -MUST include all required fields. A verifier SHOULD check that each -required field satisfies the normative requirements for that field. -Optional fields MAY -be ignored by issuers and/or verifiers. +A conforming issuer processor is a conforming +processor that produces conforming documents.
