/**
  @file mpe_derived.ddl
  @brief ddl file
  @details Defines the derived (computed) variable configuration table.  This
  drives MPE_DERIVED rows in MPE_TABLES, so that the table itself can be
  maintained through the EDIT screen with the usual approve workflow.

  Derived values are not persisted - the logic is applied at read time, before
  the filter, so that the variables can be filtered on.
