+<!-- TODO: Things which need to be done for full XInput support
+	but cannot be done now ( August 18, 2014 ) with the current feature-set
+	of the xml and the generator:
+
+*****
+
+replace "uninterpreted_data" or similar constructs
+with a semantic that shows how to interpret this data.
+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:
+* GetFeedbackControl reply field "feedbacks" ( structs FeedbackState, ... )
+* ChangeFeedbackControl request field "feedback" ( structs FeedbackCtl, ... )
+* QueryDeviceState reply field "classes" ( structs InputState, ... )
+* GetDeviceControl reply field "control"  ( structs DeviceState, ... )
+* ChangeDeviceControl request field "control" ( structs ChangeDeviceControl, ... )
+* 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
+
+This is needed for the following XI2-events ( and eventcopies thereof )
+	KeyPress
+	ButtonPress
+	RawKeyPress
+	RawKeyPress
+	RawButtonPress
+	TouchBegin
+	RawTouchBegin
+
+*****
+
+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
+"num_axes" of the GetDeviceMotionEvents-reply
+in struct DeviceTimeCoord.
+
+*****
