We usually avoid bool arguments. However this is acceptable because the callsite
doesn't use literal true/false.

If we don't use bool, we can change this to CollectionType, and assert it is
either RadioImgNodeListType or RadioNodeListType.

Hmm. And use a dynamic assert instead of the language's type system to check
that this really is a Boolean value that we're passing in? I'm not convinced
this represents a real improvement.

I've made the field const, so that no one gets the wrong idea.
