which will, e.g., be necessary for server-side xcb.
This affects the following:
-* QueryDeviceState reply field "classes" ( structs InputState, ... )
-* XIChangeHierarchy request field "changes" ( structs HierarchyChange, ... )
-* struct XIDeviceInfo field "classes" ( structs DeviceClass, ... )
* SendExtensionEvent member "events"

*****
-xml and generator should support
-switch-case similar to switch-bitcase.
-
-(and maybe: variable sized unions with a mechanism to define
-which union-field is selected.)
-
-One of these features is needed for the InputInfo type
-which is used by request "ListInputDevices" for the list "input_infos".

Parametrized structs
This is needed for being able to use the value of the field
