</span>Can we use dynamic casting of the parent resource or some other formalism to avoid the string comparison at the component level? That way things in tight loops would be fast but we would still be flexible. I worry that if we start with an enum and then add cases all the pre-existing switch statements would add fragility; people seem to deal with strings a little more defensively than enums.<br class="">
