Overview

 A layout element which can be defined by a renderer extension. The
 payload in this message will be passed verbatim to any registered renderer
 extension in the renderer. It is then expected that the extension can
 parse this message, and emit the relevant element.

 If a renderer extension is not installed, this resource will not render
 any element, although the specified space will still be occupied. If the
 payload cannot be parsed by the renderer extension, then still nothing should
 be rendered, although this behaviour is defined by the renderer extension.
