Nested Component Expansion

A nested-component specifies the component that is referenced by a nested component reference declared by the current component, and has the component resolution semantics of the <nestedRef> installed component targeter described in Chapter 2, "Installed Component Targeter" section. It has the following syntax:

	nestedRef:component-reference-name

Above, component-reference-name is the name of a <componentRef> element with "NESTED" installMode within the current component.

A nested-component may only be used when the current component is a composite component, and may only be used as a primary-component when the external component substitution reference appears within a composite component. When used as a primary-component, it may not be used as the default value of a component variable or override variable setting, as the referenced component will not yet have been installed when the variable is evaluated.
