+// TypeMeta is shared by all top level objects. The proper way to use it is to inline it in your type,
+// like this:
+// type MyAwesomeAPIObject struct {
+//      runtime.TypeMeta    `json:",inline"`
+//      ... // other fields
+// }
+// func (obj *MyAwesomeAPIObject) SetGroupVersionKind(gvk *metav1.GroupVersionKind) { metav1.UpdateTypeMeta(obj,gvk) }; GroupVersionKind() *GroupVersionKind
+//
+// TypeMeta is provided here for convenience. You may use it directly from this package or define
+// your own with the same fields.

+// RawExtension is used to hold extensions in external versions.
+//
+// To use this, make a field which has RawExtension as its type in your external, versioned
+// struct, and Object in your internal struct. You also need to register your
+// various plugin types.
+//
+// // Internal package:
+// type MyAPIObject struct {
+// 	runtime.TypeMeta `json:",inline"`
+//	MyPlugin runtime.Object `json:"myPlugin"`
+// }
+// type PluginA struct {
+//	AOption string `json:"aOption"`
+// }
+//
+// // External package:
+// type MyAPIObject struct {
+// 	runtime.TypeMeta `json:",inline"`
+//	MyPlugin runtime.RawExtension `json:"myPlugin"`
+// }
+// type PluginA struct {
+//	AOption string `json:"aOption"`
+// }
+//
+// // On the wire, the JSON will look something like this:
+// {
+//	"kind":"MyAPIObject",
+//	"apiVersion":"v1",
+//	"myPlugin": {
+//		"kind":"PluginA",
+//		"aOption":"foo",
+//	},

+// So what happens? Decode first uses json or yaml to unmarshal the serialized data into
+// your external MyAPIObject. That causes the raw JSON to be stored, but not unpacked.
+// The next step is to copy (using pkg/conversion) into the internal struct. The runtime
+// package's DefaultScheme has conversion functions installed which will unpack the
+// JSON stored in RawExtension, turning it into the correct object type, and storing it
+// in the Object. (TODO: In the case where the object is of an unknown type, a
+// runtime.Unknown object will be created and stored.)
