Investigation reveals that XML Schema 1.0 does not allow seconds in time zones anyway. So the spec and erratum 2.121 will be updated to state that for Z, ZZ, ZZZ no seconds are allowed.

I've just re-read the ICU SimpleDateFormat class entry for Z, reproduced below. I had not spotted that Z, Z, ZZZ now also imply optional seconds, and are equivalent to 'xxxx' which we said we don't support. Z 1..3 -0800 The ISO8601 basic format with hours, minutes and optional seconds fields. The format is equivalent to RFC 822 zone format (when optional seconds field is absent). This is equivalent to the "xxxx" specifier. 4 GMT-8:00 The long localized GMT format. This is equivalent to the "OOOO" specifier. 5 -08:00 -07:52:58 The ISO8601 extended format with hours, minutes and optional seconds fields. The ISO8601 UTC indicator "Z" is used when local time offset is 0. This is equivalent to the "XXXXX" specifier. We've always supported Z (as RFC 822) so we can't now drop Z 1..3.

If we think this is not needed then we could drop ZZZZZ, xxxx, xxxxx, XXXX, XXXXX, and stick with standard ISO8601. I would be happy to remove these, and I have no clue the meaning or use of a time zone with seconds. I have edited in the other ICU calendar pattern review comments, but this is outstanding.
