In Non-Storing mode DAOs are to be send unicast to the DODAG root.

It's always been unclear to me if the DODAGID must always be the IPv6 address
of the root, or if it can be an arbitrary (unique) 128-bit number. In storing
mode that works fine.

Am I missing something, or is the definition of the DODAGID in 6550 simply a
bit less specific than it should be?
