A large, undelayered specification becomes very hard to reason about, and there are many interdependencies, often undocumented or unclear during the earlier days of committee work. On such large specs, problems are either difficult to give an answer too or are so entrenched that reviews become useless: a problem is pointed out but it is too entrenched to do anything about. I think the issue is how to prevent Working Groups and specs which have little chance of producing good specifications and technologies with an open process that is responsive to reviews. >>2) Maximum two-year membership of working groups (2 years on, 2 years >>off).

But losing expertise is the point. At some stage, the young thrusting achievers become the corrupt old guard, unable and unaware of other possibilities and bound by career motives to push for the centrality of their concerns and expertise. You want some churn, fresh blood, etc. Keeping a two year group membership would alter the dynamic of spec development and encourage layered, non-monlithic specs that each were more implementable. The old guard will still be around for advise and comment. And they can join other working groups to help inter-specification cohesion. Look at XML Schemas: big fat type derivation system which is not much value (for complex types) and XQuery still needed to rework the derivations for datatypes. People think "oh we need a big spec because we need to feed back later requirements into the earlier stages" but even when they do, it still doesn't work. Cheer Rick Jelliffe
