   --  This function accepts an Element representing an expanded generic
   --  declaration as an argument and returns the generic instantiation
   --  which was expanded in the argument declaration. According to subclause
   --  15.26, this instantiation should be returned as the Enclosing_Element
   --  for the expanded generic declaration.
   --
   --  Should we move this function in Asis.Extensions?

   function Enclosing_For_Explicit_Instance_Component
     (Element : Asis.Element)
      return Asis.Element;
   --  Computes the Enclosing Element for an explicit component of an
   --  expanded generic declaration. The problem in this case is, that if
   --  the result represents the whole expanded declaration, the
   --  Special_Case field of the result should be properly set

   function Enclosing_Element_For_Explicit
     (Element : Asis.Element)
      return Asis.Element;
   --  This is the general constructor of enclosing element for explicit
   --  elements

   --  This is the general constructor of enclosing element for implicit
   --  elements. It's only partially implemented for now.

      return Asis.Element;
   --  This is the general constructor of enclosing element for elements from
   --  limited view.

   function Parent_No_Normalization (Node : Node_Id) return Node_Id;
   --  this function is the modification of Atree.Parent. It is able
   --  to deal in the "ASIS mode" with the sequences of one-identifier
   --  declarations/with clauses resulting from the normalization of
   --  multi-name declarations/with clauses which is done by the
   --  compiler
