RE: Issue with ARIA 1.1 regarding which roles include children presentational = true ?

I'm still having trouble envisioning this, can you provide a markup example?

Currently, on Windows in IE11, Firefox, and Chrome for example, all children appear to already be treated as presentational.

Basic markup example:

<div role = "tree" aria-label = "Accessible Name" id = "id1" aria-owns = "id1-1">
<div tabindex = "0" role = "treeitem" aria-expanded = "true" aria-level = "1" aria-selected = "true" id = "id1-1" aria-owns = "id2">
Branch Node
</div>
<div role = "group" id = "id2" aria-owns = "id2-1">
<div tabindex = "-1" role = "treeitem" aria-level = "2" id = "id2-1">
Child Leaf Node
</div>
</div>
</div>

So, if you add additional markup structures within that container, like so:

<div role = "tree" aria-label = "Accessible Name" id = "id1" aria-owns = "id1-1">
<h2> Some Heading </h2>
<div tabindex = "0" role = "treeitem" aria-expanded = "true" aria-level = "1" aria-selected = "true" id = "id1-1" aria-owns = "id2">
Branch Node
<ul>
<li> One </li>
<li> Two </li>
</ul>
</div>
<div role = "group" id = "id2" aria-owns = "id2-1">
<h3> Another Heading </h3>
<div tabindex = "-1" role = "treeitem" aria-level = "2" id = "id2-1">
Child Leaf Node
<a href="#"> What? </a>
<input type="checkbox" checked title="This is confusing?" />
</div>
</div>
</div>

If you test this in ATs, none of it makes any sense at all.

Bryan,

You could have an OLAP like tree with information in the leaves. For instance you could have a tree for a year. At the top node you provide the total sales for the year. The tree has a branch for each quarter. Each branch reports the total sales for the quarter. The quarters have leaves for each month with a total for the month. Inside the month is a list of week by week sales or perhaps are are 5 reports (articles) or whatever one report for each store. I have seen things like this implemented as nested lists and using the roles of tree, group and tree item are used. You can imaging a control like this appearing on an executive's dashboard.

I have also used trees as shadow DOM's for charts so AT could read the shadow DOM and get the chart information.

Bryan,

Role treeitem should not be children presentational true. A element with the role treeitem can have children that are semantically important and should be included in the accessibility tree.

Good question, I'm not sure, would be good to get others opinions about this.

I'm concerned at which level it should stop making sense, such as embedded lists, tables, etc. None of that works intuitively in a link for example.

Links can include block elements in html5.
Should those elements be ignored when they have a semantic role?
example:
<a href="#"><h2>Foo</h2</a>
Should assistive technologies expose this is an h2 link, or just as a link?
