 /**
- * A directive that adds a CSS class when a `uiSref` is active.
+ * A directive that adds a CSS class when its associated `uiSref` link is active.
  *
  * ### Purpose
  *
- * This directive should be paired with a [[UISref]], and is used to apply a CSS class to the element when
- * the state that the `uiSref` targets is active.
+ * This directive should be paired with one (or more) [[UISref]] directives.
+ * It will apply a CSS class to its element when the state the `uiSref` targets is activated.
+ *
+ * This can be used to create navigation UI where the active link is highlighted.
  *
  * ### Selectors
  *
  * - `[uiSrefActive]`: When this selector is used, the class is added when the target state or any
  * child of the target state is active
- * - `[uiSrefActiveEq]`: When this selector is used, the class is added when the target state is directly active
+ * - `[uiSrefActiveEq]`: When this selector is used, the class is added when the target state is
+ * exactly active (the class is not added if a child of the target state is active).
  *
  * ### Inputs
  *
- * - `uiSrefActive`/`uiSrefActiveEq`: one or more CSS classes to add to the element, when active
+ * - `uiSrefActive`/`uiSrefActiveEq`: one or more CSS classes to add to the element, when the `uiSref` is active
  *
- * @example
+ * #### Example:
+ * The anchor tag has the `active` class added when the `foo` state is active.
  * ```html
- *
  * <a uiSref="foo" uiSrefActive="active">Foo</a>
- * <a uiSref="foo.bar" [uiParams]="{ id: bar.id }" uiSrefActive="active">Foo Bar #{{bar.id}}</a>
  * ```
+ *
+ * ### Matching parameters
+ *
+ * If the `uiSref` includes parameters, the current state must be active, *and* the parameter values must match.
+ *
+ * #### Example:
+ * The first anchor tag has the `active` class added when the `foo.bar` state is active and the `id` parameter
+ * equals 25.
+ * The second anchor tag has the `active` class added when the `foo.bar` state is active and the `id` parameter
+ * equals 32.
+ * ```html
+ * <a uiSref="foo.bar" [uiParams]="{ id: 25 }" uiSrefActive="active">Bar #25</a>
+ * <a uiSref="foo.bar" [uiParams]="{ id: 32 }" uiSrefActive="active">Bar #32</a>
+ * ```
+ *
+ * #### Example:
+ * A list of anchor tags are created for a list of `bar` objects.
+ * An anchor tag will have the `active` class when `foo.bar` state is active and the `id` parameter matches
+ * that object's `id`.
+ * ```html
+ * <li *ngFor="let bar of bars">
+ *   <a uiSref="foo.bar" [uiParams]="{ id: bar.id }" uiSrefActive="active">Bar #{{ bar.id }}</a>
+ * </li>
+ * ```
+ *
+ * ### Multiple uiSrefs
+ *
+ * A single `uiSrefActive` can be used for multiple `uiSref` links.
+ * This can be used to create (for example) a drop down navigation menu, where the menui is highlighted
+ * if *any* of its inner links are active.
+ *
+ * The `uiSrefActive` should be placed on an ancestor element of the `uiSref` list.
+ * If anyof the `uiSref` links are activated, the class will be added to the ancestor element.
+ *
+ * #### Example:
+ * This is a dropdown nagivation menu for "Admin" states.
+ * When any of `admin.users`, `admin.groups`, `admin.settings` are active, the `<li>` for the dropdown
+ * has the `dropdown-child-active` class applied.
+ * Additionally, the active anchor tag has the `active` class applied.
+ * ```html
+ * <ul class="dropdown-menu">
+ *   <li uiSrefActive="dropdown-child-active" class="dropdown admin">
+ *     Admin
+ *     <ul>
+ *       <li><a uiSref="admin.users" uiSrefActive="active">Users</a></li>
+ *       <li><a uiSref="admin.groups" uiSrefActive="active">Groups</a></li>
+ *       <li><a uiSref="admin.settings" uiSrefActive="active">Settings</a></li>
+ *     </ul>
+ *   </li>
+ * </ul>
+ * ```
+ *
+ * ---
+ *
+ * As

+ * A directive which emits events when a paired [[UISref]] status changes.
+ *
+ * This directive is primarily used by the [[UISrefActive]]/[[UISrefActiveEq]] directives to monitor `UISref`(s).
+ * This directive shares the same attribute selectors as `UISrefActive/Eq`, so it is created whenever a `UISrefActive/Eq` is created.

+ * </li>
+ * ```

+ *
+ * A single `uiSrefStatus` can enclose multiple `uiSref`.
+ * Each status boolean (`active`, `exact`, `entering`, `exiting`) will be true if *any of the enclosed `uiSref` status is true*.
+ * In other words, all enclosed `uiSref` statuses  are merged to a single status using `||` (logical or).
+ *

+ *     <li> <a uiSref="admin.groups">Groups</a> </li>
+ *   </ul>
+ * </li>
+ * ```
+ *
+ * In the above example, `$event.active === true` when either `admin.users` or `admin.groups` is active.
