Isn't it more important for applications to know what _driver_ provides
the device, so they know about capabilities and things to set? The
_nature_ of the device seems only to be useful for displaying an image
of what the device might look like. Even if mouse, kbd and evdev provide
similar devices there might be a difference for the application. How are
combo-devices (tablet with keys through evdev) recognized and exposed to
applications? Isn't it dangerous for drivers other than evdev/mouse to
export XI_MOUSE, even if it is a mouse?

True, so I'll change that and see what it breaks.

For consistency and ease, I'm for merging it to XI.h.

But I don't think it makes much sense, if it is a per-driver setting.
Leave it to the drivers then, that makes adding new types easier.
