[CONNECT C++] DgnElementSetTool enum ErrorNums

 Class DgnElementSetTool defines enum ErrorNums...

enum ErrorNums
{
  ERROR_NUM_NoFence = 68,
  ERROR_NUM_NoFenceElems = 122,
  ERROR_NUM_NoFenceElemsOutside = 250,
  ERROR_NUM_NoSSElems = 85,
  ERROR_NUM_NotSuportedElmType = 609,
};

Those values don't appear accidental.  However, I can't see anywhere where that enum is used.
