Linux Windows 
 An interface for in-process accessibility clients
 that wish to retrieve information about a document.
 When accessibility is turned on in Gecko,
 there is an nsIAccessibleDocument for each document
 whether it is XUL, HTML or whatever.
 You can QueryInterface to nsIAccessibleDocument from
 the nsIAccessible or nsIAccessNode for the root node
 of a document. You can also get one from 
 nsIAccessNode::GetAccessibleDocument() or 
 nsIAccessibleEvent::GetAccessibleDocument()

Methods

 Returns the first accessible parent of a DOM node.
 Guaranteed not to return nsnull if the DOM node is in a document.
 @param aDOMNode The DOM node we need an accessible for.
 @param aCanCreate Can accessibles be created or must it be the first 
                   cached accessible in the parent chain?
 @return An first nsIAccessible found by crawling up the DOM node
         to the document root.
nsIAccessible getAccessibleInParentChain(in nsIDOMNode aDOMNode, in boolean aCanCreate) 
 Returns the access node cached by this document
 @param aUniqueID The unique ID used to cache the node.
                  This matches up with the uniqueID attribute on
                  nsIAccessNode.
 @return The nsIAccessNode cached for this particular unique ID.
[noscript] nsIAccessNode getCachedAccessNode(in voidPtr aUniqueID) 
 The namespace for each ID that is handed back.
AString getNameSpaceURIForID(in short nameSpaceID)
