+The following accessible states aren't translated, just ignored:
+  STATE_READONLY:        Supported indirectly via EXT_STATE_EDITABLE
+  STATE_HOTTRACKED:      No ATK equivalent.  No known use case.
+                         The nsIAccessible state is not currently supported.
+  STATE_FLOATING:        No ATK equivalent.  No known use case.
+                         The nsIAccessible state is not currently supported.
+  STATE_MOVEABLE:        No ATK equivalent.  No known use case.
+                         The nsIAccessible state is not currently supported.
+  STATE_SELFVOICING:     No ATK equivalent -- the object has self-TTS.
+                         The nsIAccessible state is not currently supported.
+  STATE_LINKED:          The object is formatted as a hyperlink. Supported via ATK_ROLE_LINK.
+  STATE_EXTSELECTABLE:   Indicates that an object extends its selection.
+                         This is supported via STATE_MULTISELECTABLE.
+  STATE_PROTECTED:       The object is a password-protected edit control.
+                         Supported via ATK_ROLE_PASSWORD_TEXT
+  STATE_HASPOPUP:        Object displays a pop-up menu or window when invoked.
+                         No ATK equivalent. The accessible state is not
+                         currently supported.
+  STATE_PINNED:          The object is pinned, usually indicating it is fixed in
+                         place and has permanence. No ATK equivalent. The
+                         accessible state is not currently supported.
+
+The following ATK states are not supported:
+  ATK_STATE_ARMED:       No clear use case, used briefly when button is activated
+  ATK_STATE_HAS_TOOLTIP: No clear use case, no IA2 equivalent
+  ATK_STATE_ICONIFIED:   Mozilla does not have elements which are collapsable into icons
+  ATK_STATE_TRUNCATED:   No clear use case. Indicates that an object's onscreen content is truncated, 
+                         e.g. a text value in a spreadsheet cell. No IA2 state.
