* directive prefixed with `*`) and have the `TemplateRef` for this Embedded View injected into 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.
