------------------------------------

             Summary: Broaden definitions of transformations topcount and bottomcount
                 Key: ODATA-1041
                 URL: https://issues.oasis-open.org/browse/ODATA-1041
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: New Feature
          Components: OData Extension for Data Aggregation
    Affects Versions: V4.0_CSD03
         Environment: Proposed
            Reporter: Gerald Krause
             Fix For: V4.0_CSD04


Definitions in section 3.2 and 3.6 state that the second parameter must result in a primitive numeric value. This is too restrictive, actually it is only required that there is a total ordering on these values.

Consider, for example, getting the latest stock by product: $apply=groupby((Product),topcount(1,Date))
