16  """This module provides references to built-in Python types. 
17   
18  In Python 2.x these are in the types module.  In Python 3. those 
19  references have been removed in favor of explicit use of the natural 
20  Python type.  We need these in contexts where the binding of the type 
21  identifier (e.g., C{int}) has changed to the class representing the 
22  XML Schema datatype of the same name (viz., C{xsd:int} or 
23  L{pyxb.binding.datatypes.int}), so provide a way to get back to the 
24  underlying Python type.
