+The Accessible interface provides for a hierarchical tree of accessible
+objects corresponding to user interface components and content in an
+accessible application. Accessible objects provide name, descriptive
+information, state information, and information on the "role" of the object in
+the user interface. The capabilities of these objects may be queried via
+interface queries, as they are implemented via interface aggregation. These
+objects are located in a containment hierarchy with parent/child
+relationships, and may have other functional relationships to objects within
+the tree.
