Embed structure in Megaco

[mwilligs@REDACTED]

We have the next megaco transaction:

Step 1
MGC to RGW:
   MEGACO/1 [216.33.33.61]:27000
   Transaction = 1234 {
       Context = - {
           Modify = TermA {
               Media {
                        LocalControl {
                            Mode = Receiveonly}
                        },
               DigitMap= Dmap1 {(2XXX)}
               Events = 1111 {
                    al/of Embed {signals {cg/dt},
                    Events=1112 {al/on},
                    {dd/ce {Dmap1}}}
           }
       }
   }

Can "signals" be an "Embed"'s parameter.
If "signals" can be an "Embed"'s parameter, how can I encode it in
Megaco-Erlang?

In Megaco-Erlang we have:

RequestedActions
{
  keepActive
  eventDM
  secondEvent
  signalDescriptor
  ...
}

In this point 'secondEvent' (Embed) and 'signalDescriptor' (Signal) are in
the same level.
But, following 'secondEvent', we have:

SecondEventDescriptor
{
  requestID
  eventList
}

there is no 'signalDescriptor' in this structure. So, is the Transaction
showed in the RFC wrong?
