Jonathan 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.

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. FYI, -- Jonathan W.
