Plugin file format - Optional element reference

Plugin applications can decide which elements can be allowed beneath a plugin element (except for the fixed set which are always included). The plugin system provides a variety of optional elements, found below. It is expected that most applications will provide all of these elements. Plugin applications may also add their own, new elements.

Check with the plugin application documentation to see which elements it allows.
