	// resource, but it may have a different kind. For instance, /pods has the resource "pods" and the kind "Pod", while
	// /pods/foo/status has the resource "pods", the sub resource "status", and the kind "Pod" (because status operates on
	// pods). The binding resource for a pod though may be /pods/foo/binding, which has resource "pods", subresource
	// "binding", and kind "Binding".
