The OptionalPlaceholder Object <ComponentsGroup> allows nesting this ObjectType to further categorize the referenced Components. It also allows adding concrete Component groups not defined by this specification.

The InstanceDeclarations of the ComponentsGroupType have additional Attributes defined in Table 16.
