 /**
  *  This class defines an abstract interface that all validators must support.
  *  When the scanner scans the attributes in a start tag, it must have a list
  *  of the defined attributes for that element. This is used to fault in
  *  defaulted and fixed attributes, to know which ones are required, and to
  *  know the their types in order to do the correct normalization.
  *
  *  Since each validator will have its own derivatives of XMLAttDef and will
  *  have its own specialized storage mechanisms for elements and the att
  *  defs that they own, there must be an abstracted way for the scanner to
  *  deal with this list.
  *
  *  It does not derive from the generic Enumerator template class, because
  *  there are portability issues with deriving from a template class in a
  *  DLL. It does though provide a similar enumerator interface.
