Tempo.Iso8601EncodeError exception (Tempo v1.0.0)

Exception raised when a Tempo value cannot be rendered as an ISO 8601 string because it contains a construct with no ISO 8601 representation.

The only such construct at present is a nearest-weekday recurrence — the cron W day-of-month modifier (15W, LW), parsed by Tempo.Cron into a :nearest_weekday selection token. Like RFC 5545 BYSETPOS/WKST it has no ISO 8601 designator; unlike those, no project-specific designator was minted for it (the equivalent day-level operation is Tempo.nearest_working_day/2). Such a value round-trips only through its cron string, not through Tempo.to_iso8601/1.
