+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_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.
