/** Finds and stores referenced action to be invoked after the actor's tag is closed and all its children are parsed. As
 * opposed to {@link OnCreateLmlAttribute}, these actions are invoked after tag is closed, rather than the actor object
 * is constructed. Multiple on close actions can be referenced with different attribute names, but their invocation
 * order is not fixed, so they should not depend on each other. This attribute expects an action ID. By default, mapped
 * to "onClose", "close", "onTagClose", "tagClose".
