           Summary: [F+O} Return type of op:subtract-dateTimes, op:subtract-
                    dates, op:subtract-times
           Product: XPath / XQuery / XSLT
           Version: Recommendation
          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Functions and Operators

The signatures of:

op:subtract-dateTimes
op:subtract-dates
op:subtract-times

all have xs:dayTimeDuration? return type.  Unless I'm mistaken, these functions
can never return the empty sequence and should therefore have return type
xs:dayTimeDuration,
