1. Introduction
[RFC8366] describes a voucher artifact used in [BRSKI] and [RFC8572]
to transfer ownership of a device to from a manufacturer to an owner.
That document defines the base YANG module, and also the initial
serialization to JSON [RFC8259], with a signature provided by
[RFC5652].
Other work, [I-D.ietf-anima-constrained-voucher] provides a mapping
of the YANG to CBOR [RFC8949] with a signature format of COSE
[RFC8812].
This document provides an equivalent mapping of JSON format with the
signature format in JOSE format [RFC7515].

This document does not extend the YANG definition of [RFC8366] at
all, but accepts that other efforts such as
[I-D.richardson-anima-voucher-delegation],
[I-D.friel-anima-brski-cloud], and
[I-D.ietf-anima-brski-async-enroll] do. This document supports
signing any of the extended schemas defined in those documents and
