CORBA26 — CCM Events issue

I was researching the CCM Event Corba 3 to Corba 2.3 mappings in
chapter 5 of Volume I, and found that the resulting interfaces did not
permit a consumer to subscribe to a publisher because the interface
type returned by the get_consumer_<name>() does not match the
subscribe_<name)() parameter. I am not sure if I made a mistake when
mapping the 3.0 to 2.3 idl or if it is a problem in the standard. I
also provide an alternative that might work, though I'm sure it will
need some work.
