The generated sample test driver does not instantiate and connect
parsers for polymorphic cases. It is generally not possible to do
since there is no way to know which types can and cannot be used
in xsi:type. You will need to add extra parser() calls with derived
types yourself.

Then you need to add:

EventMessages_p.parser (AlertOpen_p);
EventMessages_p.parser (AlertClosure_p);

To the call for EventMessage_p that is generated automatically. This
is all covered in Section 5.4, "Support for Polymorphism" in the
C++/Parser Getting Started Guide:

http://codesynthesis.com/projects/xsd/documentation/cxx/parser/guide/#5.4

As we all in the 'polymorphism' example.
