A system-type-component specifies the component derived from a given component type that is most recently installed on a particular host at a particular location, and has the component resolution semantics of the <systemType> installed component targeter described in Chapter 2, "Installed Component Targeter" section. It has the following syntax:
systemType:component-type-name
systemType:component-type-name@{path}
systemType(host-redirect):component-type-name
systemType(host-redirect):component-type-name@{path}
Here, path is optional, and if specified, indicates the path in which the desired component is installed. The host-redirect is also optional, and indicates the host on which the desired component is installed, as described in the host redirects section.
