+/**
+ * A cross-platform interface that supports platform-specific 
+ * accessibility APIs like MSAA and ATK. Contains the sum of what's needed
+ * to support IAccessible as well as ATK's generic accessibility objects.
+ * Can also be used by in-process accessibility clients to get information
+ * about objects in the accessible tree. The accessible tree is a subset of 
+ * nodes in the DOM tree -- such as documents, focusable elements and text.
+ * Mozilla creates the implementations of nsIAccessible on demand.
+ * See http://www.mozilla.org/projects/ui/accessibility for more information.
