   --  in the given architecture respect their respective semantics
   --  rules given by the AADL standard. Return True if all rules are
   --  respected.

   function Check_Connection (Node : node_id) return Boolean;
   --  Verify that the given connection respects the semantics given
   --  by the standard (type compatibility, orientation
   --  compatibility...). Return True if all rules are respected.

   --  Verify the validity of all property declarations. Return True
   --  is everything is OK, else False. Verify the type and value
   --  consistancies.
