It's a bit strange that the endpoint service provider invalidates the transport
rather than the other way around.

Right. Removed the test for this function, since ClearConfiguration will be
called in one of the following cases:
(1) Directly call SetValid on the transport object.
(2) Set the media object to be invisible. This will invalidate all transport
objects.
