// An alias owns no validator. It resolves to the cheat sheet entry through
// formatCheatSheet_resolve, so FormatCheatSheet stays the single owner of every
// format's validator and a correction to one reaches every spelling of it. The
// aliases previously carried validator strings of their own, which made each of
// them a second implementation sharing a name and free to drift: `datetime`
// emitted `format: "date-time"` while validating with `new Date`, so it accepted
// February 30th and rejected the RFC 3339 leap second the cheat sheet handles.
//
// Aliases live beside the cheat sheet so that enumerating this file enumerates
// every owner of the `@format` contract.
