Not true.

BSD also handles processes, user control, POSIX API, systems calls,  
networking and firewalls, filesystems, VFS layer, IPC, cryptography,  
and most of the synchronous I/O systems.

XNU handles the low level kernel functions like tasks, threads, memory  
protection, low level IPC, interrupts, etc.

Here's a good overview:
