CC0 1.0 Universal (Public Domain Dedication)

The conformance vector data in this directory -- A8ConformanceTest-*.txt and its
SHA256SUMS -- is dedicated to the public domain under CC0 1.0.

WHY THIS IS SEPARATE FROM THE REPOSITORY LICENCE

The surrounding package is Apache-2.0. The vectors are CC0 so that any
implementation, in any language, under any licence, can vendor them without
taking on an attribution obligation. A conformance corpus only does its job if
competing implementations can copy it freely.

The cautionary precedent is cbor/test-vectors: a standalone vector repository,
unmaintained since 2019, shipping NO LICENCE FILE AT ALL, which makes it legally
unvendorable no matter how good the data is. Licence and checksums exist here from
the first commit for that reason.
