The location in the View where the Embedded View logically belongs to.
The data-binding and injection contexts of Embedded Views created from
this TemplateRef inherit from the contexts of this location.
Typically new Embedded Views are attached to the View Container of this location, but in advanced use-cases, the View can be attached to a different container while keeping the data-binding and injection context from the original location.
