+<!-- 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:
+* SendExtensionEvent member "events"
+
+*****
+
+Parametrized structs
+
+This is needed for being able to use the value of the field
+"num_axes" of the GetDeviceMotionEvents-reply
+in struct DeviceTimeCoord.
+
+*****
