Sarah: Thank you for your comment. The rule is that the op: functions that back up operators should not accept the empty sequence since the empty sequence is handled at the language level and the function never sees it. Thus, op:subtract-dates op:subtract-times should not accept the empty sequence. The F&O Taskforce agreed to make this change on the 12/2 telcon.

Is this a bug or is there a decision behind it? The ones that can take the empty sequence are: op:subtract-dates fn:subtract-dateTimes-yielding-dayTimeDuration fn:subtract-dateTimes-yielding-yearMonthDuration op:subtract-times The ones that cannot are: op:subtract-dayTimeDuration-from-date op:subtract-dayTimeDuration-from-dateTime op:subtract-dayTimeDuration-from-time op:subtract-dayTimeDurations op:subtract-yearMonthDuration-from-date op:subtract-yearMonthDuration-from-dateTime op:subtract-yearMonthDurations --Sarah
