 This requires enhancements to the xml-schema and generator such as union with selector.
 
 This will, e.g., be necessary for automatically generated byte-order conversion code,
 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 have to support <popcount> of all members of a list
