It is quite possible for an application to be happy with having the OS save full-data archives of its data, but still need to selectively filter the set of saved files or otherwise participate in full-data backup and restore. In general we assume that any app which provides a backup agent implementation will be directly participating via the incremental key/value backup API; this new attribute allows an app to tell the OS "perform full-data backup/restore for me even though I am supplying my own agent implementation to participate."
