Section 5.3.1 in rpl-2
"9. If a node receives a RA-DIO from one of its DAG parents, and if
the parent contains a different DAGID, indicating that the
parent has left the DAG,"
Obviously, the fact that an RA does not contain DIO for a particular DAG does not mean that the node no longer belongs to that DAG. As I understand it, there is no requirement that a node include DIOs for all DAGs it belongs to in its RA. As per the draft, the node maintains a separate timer for each DAG it belongs to and generates an RA (presumably containing DIO for that DAG) when the timer fires. So, the text above needs to change.
