Seems to work just fine for me.

Well, I also have the member array explicitly listed in a DEVICE clause,
together with physical drives. So I am not really sure if the default
"DEVICE partitions" would also include MD devices.

So in my mdadm.conf I have, roughly: 

  DEVICE /dev/disk/by-id/ata-WDC_WD20EADS-*-part*
  DEVICE /dev/disk/by-id/ata-WDC_WD15EADS-*-part*
  DEVICE /dev/disk/by-id/ata-Hitachi_HDS*-part*
  DEVICE /dev/md1
  ARRAY /dev/md1 UUID=...................................
  ARRAY /dev/md0 UUID=...................................

...where md1 is a member of md0.
