ISSUE-1006: The roles that include children presentational = true are not consistent

children presentational = true not consistent

The roles that include children presentational = true are not consistent

State:
CLOSED
Product:
ARIA 1.1
Raised by:

Description:
Since I didn't get any information against, I'll file this as an official issue.

According to the children presentational description at http://www.w3.org/TR/wai-aria-1.1/#h-childrenarepresentational
Embedded child roles are not exposed by the user agent, but instead a flat labelling mechanism is used instead no matter what type of content is contained within these roles.

Currently only the following roles include this property:
button
img
math
progressbar
separator
scrollbar
slider

So this seems right, a button cannot include children with roles like link, slider, region, tablist, textbox, listbox, radio, checkbox, etc., because that wouldn't make any sense.

So, with this logic, all of the following roles should also include children presentational = true .
checkbox
combobox
menuitem
menuitemcheckbox
menuitemradio
option
radio
searchbox
spinbutton
switch
tab
textbox
treeitem

This seems logical, because none of the above roles are 'composite' widgets.
https://www.w3.org/TR/wai-aria-1.1/#composite

There is one widget exception that is not clear, role=link, which I'm not certain if this is a good idea to do or not for this role.

E.G On one side, some roles such as heading may be useful, but at the same time, embedding child widget roles is problematic as is the embedding of structural roles such as list, table, region, etc., which is confusing when encountered.

A question was raised about treeitem too, but I don't know of any markup examples where embedding roles within this widget type is a good idea.
