Action Item for   Vx+2 :      - assertions/discriminators and choice (Suman)

Attached is an example of how discriminators can be used in DFDL to identify a particular branch within choice..

                                                               could be a complex XPATH expression using XPATH functions to check for
                                                               particular pattern of data for the condition (e.g. recordType
