I already had acted on this but I understand it was not enough; So let me propose the additional diff (which is on the first mention of a RUL)

OLD

   [USEofRPLinfo] introduces the terms RPL-Aware-Leaf (RAL) and RPL-
   Unaware Leaf (RUL).  A RAL is a Leaf that injects Host routes in RPL
   to manage the reachability of its IPv6 addresses.  Conversely, a RUL
   does not participate to RPL and cannot inject its Host routes in RPL.
   The RUL therefore needs a Host-to-Router interface to advertise its
   IPv6 addresses to its access Router so the Router can inject them the
   RPL network on its behalf.  Section 5 details the interface needed by
   a router that implements this specification.

NEW

   [USEofRPLinfo] introduces the terms RPL-Aware-Leaf (RAL) and RPL-
   Unaware Leaf (RUL).  A RAL is a Leaf that injects Host routes in RPL
   to manage the reachability of its IPv6 addresses.  Conversely, a RUL
   does not participate to RPL and cannot inject routes.  Section 5
   details a Host-to-Router interface that the RUL needs to implement to
   advertise its IPv6 addresses to a Router that supports this
   specification.  The document specifies how the Router injects those
   addresses as Host Routes in the RPL network on behalf of the RUL.

Works?
