The two statements apply to different
pattern symbols. The first is for the S symbol, the second is for the I
symbol. However, it is clearer if the implementer uses the same precision
for each, so the I symbol should change to match the S symbol.

[DFDL-WG] errata
on number of fractional second digits
Sent by:
dfdl-wg-bounces@ogf.org
Not sure if this has been addressed by a subsequent
errata or not, but I just noticed something that should be corrected in
the spec.
Section 13.11.1 is on the dfdl:calendarPattern property. The following
two statements are made about the number of fractional second digits.
-
"Any number of fractional seconds "S" may by specified in
the pattern and accepted by implementations, but an implementation is free
to represent a limited number of fractional seconds internally. Excess
fractional seconds are truncated, not rounded up. At least millisecond
accuracy must be implemented." (Section 13.11.1)
-
"The number of fractional second digits supported is implementation
dependent but must be at least one." (Section 13.11.1)
These two statements are not consistent. I believe the second one
should be corrected to say that the minimum # of fractional second digits
is three (to support a minimum of millisecond accuracy).
I'm working through the last version that was put out for public comment
(v1.0.4), so my apologies if this has already been corrected.
