The OptionalPlaceholder Object<ComponentsGroup>allows nesting this ObjectTypeto further categorize the referenced Components. It also allows adding concrete Component groups not defined by this specification.
The InstanceDeclarationsof the ComponentsGroupType have additional Attributesdefined in Table 16.
