In some dialogs, there are objects exposed with role "separator" via the AT-SPI.
 These objects not only present a horizontal line, but also render text.  An
example can be found as follows:

1) Go to Tools->Options
2) Select "Paths" under the "OpenOffice.org" tree node.
3) On the right hand side will appear a table that is labeled "Paths used by
OpenOffice.org" -- this label is exposed as a "separator" object whose
accessible name matches the text being rendered.

Because it is rendering text, this object should also implement the accessible
text interface.  Thanks!
