All of the functions provided in the PD_Template library that access the ST_ExceptionList data structure use this function. Each user that accesses the ST_ExceptionList data structure directly (by avoiding the functions provided by the template) must ensure that the xInit flag in the structure is TRUE. If not, this function must be executed.
