One declaration site for the shipped lane vocabulary
The rule
Normative: this is the rule
- The lanes an implementation ships are declared in exactly one place, and every reader derives from that declaration rather than mirroring it: the derivation's range, the served payload and any picker offering an author a lane included.
- That set is what is shipped, not a ceiling: a site may add lanes of its own, so a stored lane must never be rejected merely because it is not one of the shipped ones.
Rule identifiers are permanent and are never renumbered. Each implementation publishes its own standing against these rules; this specification does not.spec 1.0-draft · SCH-36 · changed in spec 1.0
