### 26. Spell `sv_SE.personnummer` with the `+` Skatteverket uses from the year the holder turns 100, judged by a date the caller gives.
The format hard-codes `-`, and its earliest birthdate, 1930-01-01, makes the oldest draws invalid from 2030. `sv_SE.samordningsnummer` hard-codes `-` from the same date: check whether folkbokföringslagen 18 a § gives it the same `+`, since Skatteverket's SKV 704 states the rule for personnummer only. A system holding Swedish personnummer often breaks on the `+`, so a fixture carrying one is a valuable test. Whether a number takes `+` depends on the date it is read, and the decision "No builtin reads the clock, so a date is bounded by days, never by an age" forbids a builtin from reading that date off the clock. When this item is picked, first explore how a caller passes data, such as today's date, to a render: in the template, as a plain option like `WithNow` and `--now`, or both.
The format hard-codes `-`, and its earliest birthdate, 1930-01-01, makes the oldest draws invalid from 2030. A system holding Swedish personnummer often breaks on the `+`, so a fixture carrying one is a valuable test. Whether a number takes `+` depends on the date it is read, and the decision "No builtin reads the clock, so a date is bounded by days, never by an age" forbids a builtin from reading that date off the clock. Steps:
- Explore how a caller passes data, such as the date a number is read on, to a render: in the template, as a plain option, or both. Bench the spelling; `--now` reads like the clock, and only the year counts.
- Decide and document what renders when the caller gives no date, keeping seeded output stable.
- Reach birthdates back past 100 years, as Skatteverket's test series does from 1890, so a `+` ships before 2030, and decide what share of draws carries one.
- Give a path that always draws a `+` number for the date given, so a test can ask for a centenarian.
- Spell the separator with a builtin or construct a data author's own category can use too, and update the README's personnummer recipe and its "a day in 1930–2025" count.
- Check whether Lag (2022:1697) om samordningsnummer gives `sv_SE.samordningsnummer`, which also hard-codes `-` from 1930, the same `+`; Skatteverket's SKV 704 states the rule for personnummer only.

`New` and `NewTemplate` stop at the first, so data holding two mistakes takes two runs to fix. Split it into items before starting, one of them the shape a Go caller iterates and the CLI prints, and the order of an inline template's mistakes, which name no path; reword the README's "`New` refuses a mistake in the data" to every mistake.
### 88. Add a 12-digit `YYYYMMDDNNNC` form of `sv_SE.personnummer` and `sv_SE.samordningsnummer`, the form Skatteverket's test series and many systems store.
A system storing the century avoids the `+` altogether, so a fixture in that form tests the other half of the problem item 26 tests.
