[DFDL-WG] Fw: Time zones with seconds - Re: errata r14.1, and spec internal draft with these integrated in - review #3

[Steve Hanson]

I think my suggestion of not supporting time zones with optional seconds 
has put us into an inconsistent place. 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.

Made this change.

Also, updated Errata 2.3 (Unsure about the references at the top of that 
errata description.

One question - do we really need to support time zones with seconds? 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. Let's close on this on next WG call.
