We improved Microsoft Office 2000's various object models to provide more information to accessibility aids. This would allow sighted colleagues to see where information is being spoken is coming from on the screen. This would be an interesting thing to experiment with and offers promise. This is not an issue with Active Accessibility and is also available in the Dynamic HTML object model. Hopefully the DOM WG will adopt it.
None come immediately to mind.
Used for hit testing. This is vital for screen readers that use the content of the DOM - not just manipulate it for a different visual display. But we also need the seperation between structure, form and contents and we also need a standard. My questions are marked with JRG and responses from Glen Gorden are marked with GG .
