It makes no sense that you allowed 1 entry, but then disallow the
property. Either drop the 'minItems: 1' at the top level (keeping this)
or put 'maxItems: 1' here,


Hi Rob,

Will put maxItems: 1 here then.

+ clocks:

maxItems is already 2. Only need minItems.


Yes, will update for V4

You already defined the names, don't do it again. You need either
nothing or 'minItems: 2' depending on the above.


I will add minItems: 2 then, thanks!
