Tag numbers must be followed by tag content. I think an example of this could make it more obvious to CBOR library authors. Please add an example of malformed tag to RFC 7049bis Appendix G.1: * Definite length maps ... + * Tag number not followed by tag content: C0 * Indefinite length strings ... My pull request for this one-line addition is at: https://github.com/cbor-wg/CBORbis/pull/146 BTW, I finished reading 7049bis and really appreciate the improvements. I added many new unit tests to my CBOR library based on Appendix G. And I'm also finding 7049bis more helpful while implementing support for tags.
