I am a dojo fresher, Here is a mobile application which developed by Dojo Mobile.

and I found it can't work when I open the ios VoiceOver.

the data-dojo-type="dojox/mobile/ScrollableView" component can't scroll any more.

I checked the dojo website and found the solution(https://dojotoolkit.org/reference-guide/1.10/dojox/mobile/faq.html):

How do I develop applications which support iOS VoiceOver?

to set the alt, title and role attributes. VoiceOver will read widgets with these attributes set. See tests/test_a11y.html for examples. However, the value of a SpinWheel can not be read by VoiceOver in 1.8.Make sure

follow the guide I visited the page tests/test_a11y.html(https://github.com/dojo/dojox/blob/master/mobile/tests/test_a11y.html) and I do find the code include the alt,title,role attributes:

Here is the question: what's the meaning of these three attributes,can I add the attributes to every Dojo components in my code?and how to decide the value of these attributes?

and I found from the tests/test_a11y.html that some dojo components include just role attribute but some others include all the three.it makes me very confusing...:

here is My code ,how to reform it：

<div data-dojo-type="dojox/mobile/ContentPane" id="ReceiptsAttach" class="receipts">    
    <div id="receiptsAttachContent" data-dojo-attach-point="dataContent"  data-dojo-type="dojox/mobile/ScrollableView" class="selectContent"></div>

    <div style="clear:both;"></div> 
</div></div>

For title: https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/title

Contains a text representing advisory information related to the element it belongs to. Such information can typically, but not necessarily, be presented to the user as a tooltip.

for Alt: https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes

Alternative text in case an image can't be displayed.

For role, it is about Aria role. You can see: https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA

The role attribute defines what the general type of object is (such as an article, alert, or slider)

A list of roles can be found here: http://www.w3.org/TR/wai-aria/roles#abstract_roles
