Re: [Cbor] I-D Action: draft-bormann-cbor-cddl-2-draft-01.txt

[Carsten Bormann <[e-mail]>]

This draft now includes text for the results of the Thursday CDDL 2.0 design team meeting that actually have been implemented so far (cddlc 0.1.5).

The approach here is to explain the various options using examples; more rigorous specification text can be added later.

Please enjoy (and let’s have some discussion at the interim meeting on Wednesday).

Obviously, more work is needed (e.g., for some form of export control), but I think we are quite close to the Pareto 80 % already.

Grüße, Carsten
