Delete obsolete depends on your retention policy parameters, so you can't specify what precisely you want to delete in terms of archivelogs/backupsets. You could get the relevant information (maybe, depends on what you're trying to accomplish) by spooling a 'report obsolete' then editing the list and using it as the input for a a subsequent delete command.
