The v2. ABNF for signalsDescriptor is:

signalsDescriptor                                = SignalsToken LBRKT 
[signalParm *(COMMA signalParm)] RBRKT

Where you thinking of Events?

Hi,

The ABNF currenty says:

localDescriptor                          = LocalToken LBRKT octetString 
RBRKT

remoteDescriptor                                 = RemoteToken LBRKT 
octetString RBRKT

signalsDescriptor                                = SignalsToken [LBRKT 
signalParm *(COMMA signalParm)
  RBRKT]

ISSUE:

To me this means that an empty local (or remote) descriptor looks like:

Local {}

...while an empty signals descriptor looks like:

Signal

QUESTION: 

Why are curly brackets requried for an empty local/remote descriptor, but 
not for an empty signals descriptor?

Regards,

Hi,
 
In v3 the ABNF has been changed. I appologize for not mentioning that.
