 * attributes and the private attributes are shifted down again.

 * compiled against a newer version of the platform uses a new public
 * attribute that happens to have the same ID as the private attribute
 * the older platform is expecting, then the behavior is undefined.
 *
 * We get around this by detecting any newly defined attributes (in L),
 * copy the resource into a -v21 qualified resource, and delete the
 * attribute from the original resource. This ensures that older platforms
 * don't see the new attribute, but when running on L+ platforms, the
