I propose the following steps as the new description:

Deferred update behavior is invoked.

A case identifier is obtained from the case child element of the toggle  
element or otherwise from the case attribute. If no case element is  
identified by this value, then the toggle action has no effect.

The switch containing the identified case is identified.

If the switch has a caseref attribute which identifies a node, and that  
node is not readonly, then
the node is set to the value of the case identifier as if by a  
<code>setvalue</code> action.

An xforms-deselect event is dispatched to the currently selected case in  
the switch.

The selected states (not the attribute values) on the affected cases are  
adjusted to reflect the new state.

An xform-select event is dispatched to the newly identified case.

Steven
