### One rule for versions: 1.0 is the WAI1 envelope's wire version, and the standard is a Draft

- SPEC states it after its status line: `1.0` is the wire version of the `WAI1` envelope,
  carried in the manifest's `wai` member, and `1.1` that of the `WAI2` envelope (§7.1);
  neither is a release of the document. The title no longer names a version, the `wai`
  member is described as the envelope's wire version, and the passages that called the
  standard itself v1.0 say what they mean. Text that names an envelope by its wire version
  (a v1.0 `fallback`, the v1.1 wire format) is unchanged, since it follows the rule.
- The extension texts that called themselves a sub-spec of WAI v1.0 are a sub-spec of WAI.
