Setting Layer Renderability

In this example, the named layer "USABarThemeLayer" and named label source "StatesIndividualValueThemeLabelSource" will render (overriding any visibility settings in the named layer or named label source definition); however, the "USACapitalsLabelSource" named label source will not be rendered.
