; Anchoring Specification v1.3
; CDDL (RFC 8610) schema for the Proof Bundle
; https://anchoring-spec.org/v1.3/
;
; Scope note. CDDL describes CBOR and JSON data models. It is therefore
; used here only for the verifier input structure. The ledger inclusion
; proof is carried as an opaque byte string: its internal encoding is
; defined by the proof format in use and is not described by this schema.
;
; This file supersedes /v1.2/cddl/anchor-proof-bundle.cddl, which also
; defined a type AnchorProofBundle modelling the internal structure of an
; OpenTimestamps proof. That type is withdrawn; see Section 6.1. The v1.2
; file remains at its canonical URI for citation.
