A call to xname establishes a passive grab on the button device that is 
activated in the future by
the specified button being logically pressed,
the specified modifier keys being logically down,
no other modifier keys being logically down,
the
.A grab_window
being the focus window or an ancestor of the focus window
or being a descendant of the focus window that contains the pointer
and
a passive grab on the same button combination not existing on any
ancestor of
.A grab_window .
>>STRATEGY
Call xname.  Verify that the grab was correctly installed by pressing
a button to activate it, then attempting to grab the device from another
client.  Verify that the grab fails with an error of AlreadyGrabbed.

When the conditions for activating the grab are otherwise satisfied
and the button device is already grabbed,

>>STRATEGY
Establish an active grab on the target device.  Then establish a passive
grab from another client.  Press a button to activate the grab.
If the passive grab worked, the client that established the passive grab
should be able to replace it with an active grab.  If it failed, the active
grab should also fail with an error of AlreadyGrabbed.
