  "description": "Derived, state-endorsed age attestation for Utah's SEDI (Utah Code 63A-20). A selectively disclosable Aggregate ('A') section of individually-blinded boolean flags -- ageOver13/16/18/21/55/65 -- plus the holder (issuee) and an as-of date. The holder discloses only the threshold(s) a verifier needs (e.g. ageOver21 for alcohol, 63A-20-204(2)(a)) and the birth date is never involved (63A-20-301(1)(e)). An aggregate (not an attribute) section is correct for a homogeneous boolean vector: it treats the thresholds as an unordered blinded set, matching the ISO mDL age_over_NN element and leaving room for a sparse-Merkle-tree upgrade (PR WebOfTrust/keripy#1505; this.i @sdav5t).",
