Ok, but that's not what I wrote. I don't agree with this requirement which says that it MUST be possible for a server to support different revisions of a given module (again, if this is not the intention of the text, please clarify). I simply don't think that this is a good requirement. /martin > I have not seen a proposal that addresses all requirements and hence > at the end the WG needs to decide which tradeoffs make sense. > > /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
