Hi all,

rules for elements with host language semantics for hidden

My understanding of the clarifications to the ARIA implemantion guide[1]

* Any element that is directly hidden visually through the use of things
like CSS display:none an visibility:hidden must not be exposed to the
platform accessibility API
* This would include the HTML5 hidden attribute as the implementations use
CSS display:none
* Anything that is defined as hidden through aria-hidden SHOULD NOT be
* Relationship attributes (e.g. aria-describedby) can reference hidden
elements, the hidden elements text content will be exposed, but the
elements will not be represented in the accessibility tree.
