  35 <!-- TODO: Things which need to be done for full XInput support
  36         but cannot be done now ( August 18, 2014 ) with the current feature-set
  37         of the xml and the generator:
  38
  39 *****
  40
  41 replace "uninterpreted_data" or similar constructs
  42 with a semantic that shows how to interpret this data.
  43 This requires enhancements to the xml-schema and generator such as union with selector.
  44
  45 This will, e.g., be necessary for automatically generated byte-order conversion code,
  46 which will, e.g., be necessary for server-side xcb.
  47
  48 This affects the following:
  49 * GetFeedbackControl reply field "feedbacks" ( structs FeedbackState, ... )
  50 * ChangeFeedbackControl request field "feedback" ( structs FeedbackCtl, ... )
  51 * QueryDeviceState reply field "classes" ( structs InputState, ... )
  52 * GetDeviceControl reply field "control"  ( structs DeviceState, ... )
  53 * ChangeDeviceControl request field "control" ( structs ChangeDeviceControl, ... )
  54 * XIChangeHierarchy request field "changes" ( structs  HierarchyChange, ... )
  55 * struct XIDeviceInfo field "classes" ( structs DeviceClass, ... )
  56 * SendExtensionEvent member "events"
  57
  58 *****
  59
  60 xml and generator have to support <popcount> of all members of a list
  61
  62 This is needed for the following XI2-events ( and eventcopies thereof )
  63         KeyPress
  64         ButtonPress
  65         RawKeyPress
  66         RawKeyPress
  67         RawButtonPress
  68         TouchBegin
  69         RawTouchBegin
  70
  71
  72 *****
  73
  74 <sumof> should support fields of listmembers.
  75
  76 This is needed for request "ListInputDevices"
  77
  78 *****
  79
  80 xml and generator should support
  81 switch-case similar to switch-bitcase.
  82
  83 (and maybe: variable sized unions with a mechanism to define
  84 which union-field is selected.)
  85
  86 One of these features is needed for the InputInfo type
  87 which is used by request "ListInputDevices" for the list "input_infos".
  88
  89 *****
  90
  91 Parametrized structs
  92
  93 This is needed for being able to use the value of the field
  94 "num_axes" of the GetDeviceMotionEvents-reply
  95 in struct DeviceTimeCoord.
