IMHO I think that the SMR should go into the control-plane document. I
believe that there are many cases (specially from an SDN point of
view) where you may want to send SMRs from entities other than xTRs.

There's already a draft [1] that proposes that SMRs can also be sent
by MSMRs. That draft is documenting what has been implemented and
running on OpenDaylight for a while now.

Furthermore, lig-lispmob [2] supports sending SMRs on demand through a
CLI without running an xTR. I've found that capability useful on many
occasions.
