//
// Note that, if you need to copy sub-objects that didn't change, you can use the

// Additionally, all conversions started by Scheme will set the SrcVersion and
// DestVersion fields on the Meta object. Example:
//
// s.AddConversionFuncs(
// func(in *InternalObject, out *ExternalObject, scope conversion.Scope) error {
// // You can depend on Meta() being non-nil, and this being set to
// // the source version, e.g., ""

// // You can depend on this being set to the destination version,
// // e.g., "v1".
// s.Meta().DestVersion
// // Call scope.Convert to copy sub-fields.
// s.Convert(&in.SubFieldThatMoved, &out.NewLocation.NewName, 0)
// return nil
// },
// )
//
// (For more detail about conversion functions, see Converter.Register's comment.)
//
// Also note that the default behavior, if you don't add a conversion function, is to
// sanely copy fields that have the same names and same type names. It's OK if the
