If the RFC Editor uses one base document as the origin for all versions that they publish, then that document is both canonical and archival. What were you thinking would be different? Archival has to be durable and readable for several centuries. That is a stronger constraint than I think will apply elsewhere in our world. >> In the end, the canonical format may turn out to be an >> abstraction, and the real-world requirement is something that >> is functionally equivalent to the canonical format. > > That seems.... obscure. Yes, maybe - but the point is that we need to define a set of metadata requirements that can be explicit or implicit in the actual file; the implicit metadata are only present in the abstraction. I would prefer all metadata to be explicit, to avoid this problem.
