The department verifies and endorses exactly the statutory attribute set -- name, birth date, image, Utah residence address (63A-20-301(2)(f)) -- carried in an attribute ('a') section as individually-blinded, partially-disclosable nested blocks, so a holder discloses an arbitrary subset by label (e.g. prove Utah residence without the street line). An attribute section (not an aggregate) is correct for a fixed set of meaningfully-labeled fields: label-based pathing for graduated-disclosure negotiation, with no advantage to hiding block labels/positions (PR WebOfTrust/keripy#1505; this.i @sdav5t).",
