+ A wx.DataFormat is an encapsulation of a platform-specific format
+ handle which is used by the system for the clipboard and drag and
+ drop operations. The applications are usually only interested in,
+ for example, pasting data from the clipboard only if the data is
+ in a format the program understands. A data format is is used to
+ uniquely identify this format.
+
+ On the system level, a data format is usually just a number
+ (CLIPFORMAT under Windows or Atom under X11, for example).
