scrolling and scroll bars

Matt and Bryan,

For APA I have a task to review CSS Overflow Module Level 3. A main feature
of this doc is defining and handling of scrollable areas. How does AT
report scrollbars and is it important for a non-sighted user to know
whether an area is scrollable or not?  Another issue is do AT's report info
that is visually clipped, that is does the AT read the data as if it
weren't visually clipped or does it somehow try to represent only what is
visible?
