+ * the constructor of the directive using the `TemplateRef` Token. Alternatively you can query for
+ * the `TemplateRef` from a Component or a Directive via {@link Query}.
+ *
+ * To instantiate Embedded Views based on a Template, use
+ * {@link ViewContainerRef#createEmbeddedView}, which will create the View and attach it to the
+ * View Container.
