True dat.

Hi Ihe,

      <benefitStartDate>20170101</benefitStartDate>,<benefitEndDate>20170301</benefitEndDate>,
      <benefitStartDate>20170101</benefitStartDate>,<benefitEndDate>20170501</benefitEndDate>
    )/distinct-values(.)

is not the same as:

    distinct-values(
      <benefitStartDate>20170101</benefitStartDate>,<benefitEndDate>20170301</benefitEndDate>,
      <benefitStartDate>20170101</benefitStartDate>,<benefitEndDate>20170501</benefitEndDate>
    )

Which returns the distinct-values for a sequence of elements.

Your code returns the distinct-values for each of these (singleton) elements, it is like calling:

    (
      distinct-values(<benefitStartDate>20170101</benefitStartDate>),
      distinct-values(<benefitEndDate>20170301</benefitEndDate>),
      distinct-values(<benefitStartDate>20170101</benefitStartDate>),
      distinct-values(<benefitEndDate>20170501</benefitEndDate>)
    )


Another variant, that returns the result you expected is:

    (
      <benefitStartDate>20170101</benefitStartDate>,<benefitEndDate>20170301</benefitEndDate>,
      <benefitStartDate>20170101</benefitStartDate>,<benefitEndDate>20170501</benefitEndDate>
    ) => distinct-values()


Best
