Just one caveat:  you cannot define a class within an external method and 
then return an instance of that class (the routine that invoked the external 
method will not have any reference to the instance's class).

If you want to create your own object classes then put the class definitions 
in a Zope Product.  You can then access that class from within an external 
method and then return instances of the class to the routine that called the 
external method (the calling routine will be able to reference the class 
because of the Zope Product).
