When should Group be used vs. List? The distinction between them is explained briefly but more guidance and examples are needed. List appears to be broader, whereas Group only lists five "member" types (though the rationale for allowing these five types, but no others, is unclear). Why can there be a group of medications, but not a group of observations or conditions, for example? What would be the negative consequence of using the "wrong" resource – e.g., a medication "group" instead of a medication "list?"
