The record has only -- one discriminent, which contains the kind of the node. There is -- currenlty no variant (but this can change, this is not public). -- The root of a semantic tree is a library_declaration. -- All the library_declarations are kept in a private list, held by -- package libraries. -- Exemple of a tree: -- library_declaration -- +-- design_file -- +-- design_unit -- | +-- entity_declaration -- +-- design_unit -- +-- architecture_declaration -- ... -- Since the tree can represent all the libraries and their contents, it -- is not always loaded into memory. -- When a library is loaded, only library_declaration, design_file, -- design_unit and library_unit nodes are created.
