CORBA35 — TypedConsumerAdmin interface (4.9.2))

Summary: in section 4.9.2 last paragraph:

"Such a ProxyPushSupplier is guaranteed only to invoke operations defined in
interface I. Any event on the channel that does not correspond to an
operation defined in interface I is NOT passed on to the consumer. Such a
ProxyPushSupplier is therefore an event filter based on type".

My question is: if we have this proxy to block generic calls (push() in this
case) why does TypedPushConsumer inherit CosEventComm::PushConsumer, whish does
support push() ? Why should the generic calls like push() be blocked anyway
if (according to 4.7.1) TypedPushConsumer should support both typed and generic
models ?

Is there something I am misunderstanding ?
