It depends on what you want to do.
The UIElement Inspector from Apple is a screen reader in the sense that it
cares only about what's under the mouse. It only has to read the tree from a
leaf down to the root and doesn't need to know anything about "children." It
does have to use the "parent," because some of the accessibility API
requires you to have the root application UIElement.
I'm writing a browser, which reads the target application's capabilities
without having to look at the GUI onscreen. So I only have to read the tree
from the root up to its leafs and don't need to know anything about the
"parent." I need the "children" in order to find out details about
UIElements that I would like to control -- I can't find them under the mouse
because I'm not relying on the mouse.
