+The wxAccessible class allows wxWidgets applications, and
+wxWidgets itself, to return extended information about user interface elements
to client applications such as screen readers. This is the
-main way in which wxWindows implements accessibility features.
+main way in which wxWidgets implements accessibility features.
At present, only Microsoft Active Accessibility is supported
by this class.
For details on the semantics of functions and types, please refer to the
Microsoft Active Accessibility 1.2 documentation.
-This class is compiled into wxWindows only if the wxUSE\_ACCESSIBILITY setup

Functions return a wxAccStatus error code, which
may be one of the following:
