A.18.17 The Generic Package Containers.Indefinite_Multiway_Trees
The language-defined generic package Containers.Indefinite_Multiway_Trees 
provides a multiway tree with the same operations as the package Containers.Multiway_Trees 
(see 
A.18.10), with the difference that 
the generic formal Element_Type is indefinite. 
 
Static Semantics
The declaration of 
the generic library package Containers.Indefinite_Multiway_Trees
 
has the same contents and semantics as Containers.Multiway_Trees except:
 
The generic formal Element_Type is indefinite.
The procedure with 
the profile: 
procedure Insert_Child (Container : in out Tree;
                        Parent    : in     Cursor;
                        Before    : in     Cursor;
                        Position  :    out Cursor;
                        Count     : in     Count_Type := 1);
is omitted.
The actual Element parameter of access subprogram 
Process of Update_Element may be constrained even if Element_Type is 
unconstrained.
The operations Append_Child, Insert_Child, Prepend_Child, 
and Replace_Element that have a formal parameter of type Element_Type 
perform indefinite insertion (see 
A.18).
