Using the above syntax, how do you distinguish between [] at the start
of the message from actualy SD-ID data?

I think what's missing from the above, is a ':' and the syntax should
be:

<PRI>VERSION TIMESTAMP HOSTNAME APP-NAME PROCID [SD-ID]: MSG

The protocol document needs to outlaw ':' being in any field before
the MSG.

If you mark "VERSION", "PROCID" and "SD-ID" data as all being optional
then the format comes back to being very close to what's in use today.

Well, without the ':' to say where the MSG starts, I'd have argued
"How do you tell where SD-ID ends and MSG starts?" vs there just being
a string of bad SD-ID data following some good SD-ID data.

As for "but the SD has important information and the MSD does not",
that's simply a matter of how you structure the message.

It's also how data gets escaped, in general, in Internet stuff.

I'd like to see NUL outlawed from messages.
