public interface Producer
extends Visitor

Object Producer interface.

A producer is a Visitor that "produces" a named object that is added to the ExecutionContext for use by a Consumer of some sort. Note that a Visitor does not qualify as a producer just because it "produces" something. It is only a producer if it produces something that is added to the ExecutionContext for use by a Consumer.

The Producer/Consumer interfaces allows us to order the execution of multiple Visitor instances, targetted at the same element selector, based on what the Visitor produces and/or consumes.
