Speaking for myself, breaking down ECA logic or ECA paradigm, extracting policy variable from the event, Mapping Policy Variables to XPath Variables, using standard function call defined in ECA XPath Function Library will guarantee us to create an interoperable standard, the last one is the most important one, I think that is the key difference with the previous attempts. We spent a quite a lot of time to discuss this and got this agreed in the design team.

I would have expected that the senior IETF people mentioned as co-authors or contributors, who are very well familiar with the relevant history (Benoit Claise, Andy Bierman, Alex Clemm), would have explained here (or in the document) why this approach to create an interoperable standard for ECA has potential to succeed given the limited success of the prior attempts. Adopting this work without having answered this question seems premature. If the proponents of this work do not have an answer to this question, the WG will likely not find one either. /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1 | 28759 Bremen | Germany Fax: +49 421 200 3103 <https://www.jacobs-university.de/> _______________________________________________ netmod mailing list netmod@ietf.org https://www.ietf.org/mailman/listinfo/netmod _______________________________________________ netmod mailing list netmod@ietf.org https://www.ietf.org/mailman/listinfo/netmod
