| Abstract base class for value objects that provide callers into a flow
execution information about a logical response to issue and the data
necessary to issue it.
This class is a generic marker returned when a request into an executing flow
has completed processing, indicating a client response needs to be issued. An
instance of a ViewSelection subclass represents the selection of a concrete
response type. It is expected that callers introspect the returned view
selection instance to handle the response types they support.
