/**
 * A DI token representing a string ID, used
 * primarily for prefixing application attributes and CSS styles when
 * {@link ViewEncapsulation#Emulated} is being used.
 *
 * The token is needed in cases when multiple applications are bootstrapped on a page
 * (for example, using `bootstrapApplication` calls). In this case, ensure that those applications
 * have different `APP_ID` value setup. For example:
 *
 * ```ts
 * bootstrapApplication(ComponentA, {
 *   providers: [
 *     { provide: APP_ID, useValue: 'app-a' },
 *     // ... other providers ...
 *   ]
 * });
 *
 * bootstrapApplication(ComponentB, {
 *   providers: [
 *     { provide: APP_ID, useValue: 'app-b' },
 *     // ... other providers ...
 *   ]
 * });
 * ```
 *
 * By default, when there is only one application bootstrapped, you don't need to provide the
 * `APP_ID` token (the `ng` will be used as an app ID).
