/**
 * <p>
 * The <a4j:region> component specifies a part of the JSF component tree to be processed on the server.
 * The region causes all the a4j and rich Ajax controls to execute: decoding, validating, and updating the model.
 * The region causes these components to execute even if not explicitly declared. As such, processing areas can more
 * easily be marked using a declarative approach.
 * </p>
 * <p>
 * Regions can be nested, in which case only the parent region of the component initiating the request will be processed.
