I initially didn't agree with this idea, but I can see how it would make the security properties much easier to define. However, I don't think that was the intention of the current document. --Paul Hoffman, Director --VPN Consortium _______________________________________________ IPsec mailing list IPsec@ietf.org https://www.ietf.org/mailman/listinfo/ipsec
