52
53    <p>This interface serves two purposes: On the one hand it gives access
54    to the tree structure in which all accessible objects are
55    organized. Each node in this tree supports this interface.  On the other
56    hand it gives access to objects that expose the represented content.
57    That are role, state, name, description, and relations to other objects.
58    Take an OK button of a dialog as an example.  Its role is
59    <const>AccessibleRole::BUTTON</const>, its name is 'OK', and its description
60    is something like 'Accepts all changes made in the dialog'.</p>
