12 `iron-a11y-announcer` is a singleton element that is intended to add a11y

13 to features that require on-demand announcement from screen readers. In

14 order to make use of the announcer, it is best to request its availability

15 in the announcing element.

16

17 Example:

18

19 Polymer({

20

21 is: 'x-chatty',

22

23 attached: function() {

24 // This will create the singlton element if it has not

25 // been created yet:

26 Polymer.IronA11yAnnouncer.requestAvailability();

27 }

28 });

29

30 After the `iron-a11y-announcer` has been made available, elements can

31 make announces by firing bubbling `iron-announce` events.

32

33 Example:

34

35 this.fire('iron-announce', {

36 text: 'This is an announcement!'

37 }, { bubbles: true });

38

39 Note: announcements are only audible if you have a screen reader enabled.
