Ah, okay. Tablet/stylus is mentioned (rather than mouse) in the
introduction. The part on pointer events says

  Many systems support pointer devices such as a mouse, trackball,
  stylus or joypad. On systems which use a mouse, pointer events consist
  of actions such as mouse movements and mouse clicks. On systems with a
  different pointer device, the pointing device often emulates the
  behavior of the mouse by providing a mechanism for equivalent user
  actions, such as a button to press which is equivalent to a mouse
  click.

  One difference between stylus-based pointers and mouse-based pointers
  is that for a mouse, the cursor always has a position; for a stylus
  which may be lifted, the cursor may only have a position when the
  stylus is tapped on the screen. thus, content which assumes that all
  pointer devices will generate mouseIn and mouseOut events will not
  work on all devices.

So I think this is already covered.
