  --+ Test_point - (050200_020401) " If the reserved word others is supplied
  --  as the instantiation list in the component specification in an
  --  configuration specification, then the configuration specification applies
  --  to instances of the specified component whose labels are declared in
  --  the immediately enclosing declarative region, provided that each such
  --  component instance is not explicitly named in the instantiation list
  --  of a previous configuration specification."
  --
  --+ Test_objective (1)- Test that if reserved word others is supplied
  --  as the instantiation list in the component specification in an
  --  configuration specification, then the instances of the specified
  --  component whose labels are declared in the immediately enclosing
  --  declarative region, are not explicitly named in the instantiation
  --  list of a previous configuration specification.
  --  This test should not indicate an error.
