------------------------------------------------------------------------------
--  Returns True if it is possible to detect usage of named notation.
--
--  Returns False if this implementation will always change parameter lists
--  using named notation to positional lists in function, subprogram, and
--  entry calls.  In that case, the Formal_Parameter query will always return
--  a Nil_Element unless the parameter list is obtained with Normalized = True.
--
--  This function affects association lists for aggregates, instantiations,

------------------------------------------------------------------------------
--  It is not possible to obtain either a normalized or
