| States and Properties module | User Agent mapping via MSAA |
| disabled | MSAA:STATE_SYSTEM_UNAVAILABLE |
| checked | MSAA: STATE_SYSTEM_CHECKED |
| expanded | *If the hidden property is set to true : MSAA:STATE_SYSTEM_COLLAPSED. *If the hidden property is set to false: MSAA:STATE_SYSTEM_EXPANDE |
| haspopup *This state should be mapped to true on Windows systems when an event handler has a role of pop-up menu. | MSAA: haspopup |
| invalid | MSAA: no mapping - In the case of MSAA the user agent should provide a specialized API to return its value. Alternatively, if the user agent provides a specialized API for [XForms] it may provide invalid(), outOfRange(), or empty() (returns true when required but not available). This information is computed from the instance data associated with the form element. |
| multiselectable | MSAA:STATE_SYSTEM_EXTSELECTABLE |
| pressed | MSAA: STATE_SYSTEM_PRESSED is true when checked. |
| readonly | MSAA:STATE_SYSTEM_READONLY |
| required | MSAA: There is no mapping. User agent must make available through the [DOM] or a specialized API.Note: While optional could be combined with required this is kept to be consistent with CSS3 pseudo classes and [XForms]. |
| selected | MSAA:STATE_SYSTEM_SELECTED |
| unknown | MSAA:mixed |
| value | MSAA: should return the value for getValue(). |
