* A DI Token representing a unique string id assigned to the application by Angular and used
* primarily for prefixing application attributes and CSS styles when
* {\@link ViewEncapsulation#Emulated ViewEncapsulation.Emulated} is being used.
*
* If you need to avoid randomly generated value to be used as an application id, you can provide
* a custom value via a DI provider configuring the root {\@link Injector}
* using this token.
