//  2. Inconsistent validation.  Because the usages are different, the validation rules are different by usage, which makes it hard for users to predict what will happen.
//  3. The fields are both imprecise and overly precise.  Kind is not a precise mapping to a URL. This can produce ambiguity
//     during interpretation and require a REST mapping.  In most cases, the dependency is on the group,resource tuple
//     and the version of the actual struct is irrelevant.
