 *Event Transformers* occupy both roles, accepting calls to the Events Interface and transforming them into (other) calls to another Events Consumer.
 
 For example the `tao::json::events::from_value()` function is an Events Producer that takes a Value object of type `tao::json::basic_value< Traits, Base >` for any Type Traits class `Traits` and Value base class `Base` as input, and generates Events depending on the contents.
