The

KeyCodes, one for each modifier in the order
.S Shift ,
.S Lock ,
.S Control ,
.S Mod1 ,
.S Mod2 ,
.S Mod3 ,
.S Mod4 ,
and
.S Mod5 .
>>ASSERTION Good A
When a zero KeyCode occurs in a set, then it is ignored.
>>STRATEGY
>># This is not really true in any sense that we can test.
>># Check that 0 does not generate BadValue when used multiple times.
Set up a mapping with all keycodes zero.
Set mapping with xname.

>>ASSERTION Bad C
When an implementation restriction on which keys can be used
as modifiers is violated,
then a call to xname returns
.S MappingFailed
and none of the modifiers are changed.
>>STRATEGY
Try in turn all possible keycodes.
If all return MappingSuccess:
  Report unsupported.
else
  Verify that MappingFailed is returned.
  Verify that modifier has not been set to this keycode.

>>ASSERTION Bad B 3
When the new KeyCodes specified for a modifier differ from those
currently defined and any of the
current or new keys for that modifier are
in the logically down state, then a call to xname returns
.S MappingBusy
and none of the modifiers are changed.
>>STRATEGY
If extension available:
  Get current modifier mapping (other tests may have changed it from origmap).
  Make a new modifier map by permuting the old.
  Check there is at least one non-zero keycode in it.
  Simulate pressing this key using extension.
  Call xname to set the new mod. map.
  Expect MappingBusy
  Release all keys.
  Get current mapping with XGetModifierMapping.
  Compare with that got at first.
  Remove key from map.
  Simulate pressing key not in the map.
  Call xname.
  Expect MappingBusy as one of current (at time of xname call) mod keys pressed.
  Release all keys.
  Call xname to set up map to not include this key.
  Expect MappingSuccess.
  Simulate pressing key not in the map.
  Call xname.
  Expect !MappingBusy as key not in current or new maps (at time of xname call).
  Release all keys.
else
  Report untested.
