Thanks Rob. One question on setting "minItems: ". Please see below.

As the earlier version of base schema doesn't have "minItems: " set, should it be set to 0 for backward compatibility?  Or can it just be omitted setting in base schema as before?

"else" part to set "maxItems: 1" and setting "maxItems: 2" in base schema is clear to me.
