[ns] Is there HLA interface in NS?

Is there HLA interface in NS2 or NS3? We know that there is HLA module
in OPNET and Qualnet.
HLA is an IEEE standard about how to enable diffirent simulation
softwares to incooporate each other in the simulating real time. For
example, connect Qualnet with Stage using pRTI1516, the net simulation
will be able to tell us about how communications effect the command
and control of the commander, how communications affect the UAV
striking the targets, etc. Btw, Stage is a simulation tool about
CGF(computer generated forces), and pRTI1516 is an soft bus adopted
the HLA IEEE 1516 standard.
There is HLA module in OPNET, but i do not find anything about HLA in
the NS manual, Is there any HLA interface developed by third party for
NS?
