Question on aria-hidden nesting

Greetings

Can aria-hidden="false" be used on children of elements with aria-hidden="true"?
<code>
<div aria-hidden="true">
content
<div aria-hidden="false" role="dialog">
Visible dialog content
</div>
more parent div content.
</div>

One use case is implementing a modal using an in-page element (when
creating a separate div for modal dialog content is not possible).
The spec is not explicit on this, though the definition says that
:the element and all of its descendants are invisible to assistive
technologies).
http://www.w3.org/WAI/PF/aria-1.1/states_and_properties#aria-hidden

This technique does not work with screen readers currently, but we
have not yet investigated where the problem lies, and I am not 100%
sure is a problem, or if not being able to override aria-hidden state
for a descendant of aria-hidden="true" element is expected behavior.
Thanks
