The serialization example, test_no_rtti.cpp, appears to only write the base 
class XML element when saving from the base class pointer.

*** why does this appear to be so?

Perhaps I am misunderstanding the point of the extended_type_info classes 
but I thought it was a way to serialize classes with a common base class 
without having to know the type of the derived class.

*** Your understanding of the intent of the test/demo is correct.

The example in test_no_rtti.cpp clips the derived portion of the class when 
serializing from a base class pointer. Please advise.
Thanks.

*** I'm not seeing this.  I just ran it with the debugger and trapped on all 
the serialize functions of both derived classes.
