Something like: “Implementations SHOULD use the algorithm in Section xxx, but MAY user their own following the guidelines in Section yyy to ensure interoperability” I will rewrite the draft to ensure the guidelines for not breaking interoperability stands out more clearly, and move the algorithm from appendix into main.
