Section 2.9 says:

2.9. OSPF RPC Operations 

The "ietf-ospf" module defines two RPC operations:

clear-database:
    Resets the contents of a particular OSPF LSDB, forces neighbor
 adjacencies to the 'DOWN' state, and reoriginates self-originated
 LSAs. 
clear-neighbor:
    Resets a particular OSPF neighbor or group of neighbors
 associated with an OSPF interface. 

  rpcs:
    +---x clear-neighbor
    |  +---w input
    |     +---w routing-protocol-name
    |     +     -> /rt:routing/control-plane-protocols/
    |     +         control-plane-protocol/name
    |     +---w interface?               if:interface-ref
    +---x clear-database
       +---w input
          +---w routing-protocol-name
                -> /rt:routing/control-plane-protocols/
                    control-plane-protocol/name

It should say:

For OSPF RPC operations, besides routing-protocol-name - which is in
fact the OSPF instance name and could be named as instance-name -
we would need to specify the instance-type (ospfv2 or ospfv3) too.
Without this, RPC cannot handle the situation of having an OSPFv2
and OSPFv3 process with the same name. Using the same name is
not restricted by config part of the yang OSPF tree, as type/name
are the keys of an OSPF instance.

Notes:

There could be ambiguity if the same name is used since both "type" and "name". Adding the optional 'w type?' seems to be feasible and backward compatible augmentation to resolve the Errata.
