There's a point that I think should be made here, something like: In practice, interoperable implementations are commonly based on Proposed Standard documents, so whatever design defects those documents have tend to become part of the interoperable network, perhaps in the form of work-arounds. Similarly, in today's Internet, any security defects tend to be exploited at an early stage. Fixing design and security issues in widely deployed code may be difficult or impossible in practice. Therefore, there is now very strong pressure to make the Proposed Standard as mature as possible, rather than being just good enough to meet the RFC 2026 requirements. > The result is that IETF Proposed Standards > approved over the last decade or more have had extensive > review. Exactly. Brian
