CWG 2023-02-07: Reviewed; needs updates.

jensmaurer commented 1 year ago

CWG reflector discussion starting 2023-04-09: There are several (more or less general) avenues to deliver the desired feature. A revision of the paper should contain a discussion of the various options (with examples), which CWG will briefly review and then forward to EWG to make a choice.
