The CDDL which is being extended is defined in https://tools.ietf.org/html/draft-ietf-anima-grasp-15#section-5, and that draft is fully approved but waiting in MISSREF limbo. I don't have any concerns about the BRSKI CDDL because I did a toy implementation (Pledji.py, Procksy.py and Reggie.py at https://github.com/becarpenter/graspy). The CDDL in the draft has changed very slightly since then; when I have some free time I can update my Python code, but the differences are negligible. [Side note: I don't think anybody would claim that they can automatically generate running code from CDDL yet. If that becomes realistic, it would be the acid test for CDDL used in protocol specs. But it's quite a way in the future, IMHO.] Regards Brian _______________________________________________ Anima mailing list [email protected] https://www.ietf.org/mailman/listinfo/anima
