Hi, Pete.
What's the difference between IATable::modelChange and object
attributes for out-process AT? If we'll start to expose object
attributes then should set their values before we fire event but when
we need to drop their values?
If I have
<table>
<tr>
<th>caption1</th>
</tr>
<tr>
<td>cell1</td>
</tr>
</table>
then the first tr element should implement IAccessibleTable, text of
th element is COLUMN header description, the first tr element is ROW
header. Or?
Alex.
