Hi Alvaro,

But if you express even disc= reet=C2=A0metadata types in RTs no new signalling is needed. RTC can be use= d as is.=C2=A0

See most implementations can handle= RT filtering fast and efficiently.=C2=A0

Adding n= ew SAFI to signal RTs seems to me like adding complexity for no good reason= .=C2=A0

Thx,
R.

Yes, that is the ultimate goal, which is also= why a new SAFI is needed.
