 * 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()
 * @status UNDER_REVIEW
[scriptable, uuid(81ddd75f-adbd-4a1c-b87c-6522bcea0596)]
interface nsIAccessibleDocument : nsISupports
   * The URL of the document
  readonly attribute AString URL;

   * The title of the document, as specified in the document.
  readonly attribute AString title;

   * The mime type of the document
  readonly attribute AString mimeType;

   * The doc type of the document, as specified in the document.
  readonly attribute AString docType;

   * The nsIDOMDocument interface associated with this document.
  readonly attribute nsIDOMDocument document;

   * The nsIDOMWindow that the document resides in.
  readonly attribute nsIDOMWindow window;

   * The namespace for each ID that is handed back.
  AString getNameSpaceURIForID(in short nameSpaceID);

   * The window handle for the OS window the document is being displayed in.
   * For example, in Windows you can static cast it to an HWND.
  [noscript] readonly attribute voidPtr windowHandle;

   * 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.

   * 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.

   * A bit flag representing the type of ARIA properties which should be
   * checked in this document:
   * either eUnknownPropType, eCheckNamespaced, eCheckHyphenated or eCheckAny
  readonly attribute unsigned long ariaPropTypes;
   * Check attributes in the form of:
   * [someprefix]:[propname]  (e.g. aria:live) where ancestor defines: 
   * xmlns:[someprefix]=""
  const unsigned long eCheckNamespaced = 1;
   * Check hyphenated attributes in the form of aria-[propname].
   * This is the default in text/html documents.
   * Can be combined with eCheckNamespaced flag. This may
   * change during the life of the document, if setAttributeNS()
   * is used to set an ARIA property.
