What a verifier asks for.
namespaces (namespace → element ids) is the precise form and wins when non-empty — use it for any document whose elements span namespaces (e.g. an ISO 23220 credential with its own namespace). Otherwise attributes are requested in the ISO 18013-5 mDL namespace; both empty means the SDK's default mDL element set.
