Subject: [Megaco] Empty descriptor

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,
