[exim] Bug or Design? Transport name cannot begin with numbe…

I am running Exim 4.77 on FreeBSD 8.x

I decided to create a special purpose transport, viz:

587_remote_smtp:
driver = smtp
port = 587

It appears that Exim doesn't like it:

gw# /usr/local/etc/rc.d/exim restart
Stopping exim.
Starting exim.
2012-03-14 15:45:49 Exim configuration error in line 1385 of
/usr/local/etc/exim/configure:
option setting expected: 587_remote_smtp:
/usr/local/etc/rc.d/exim: WARNING: failed to start exim

This behaviour is reproduceable as long as you start a transport name with
a digit.

However, if I a transport name begins with an alphabet character instead of
a numeral, then Exim is okay with it.

Is this by design?? I couldn't find anything in spec.txt that clarifies
this behaviour.
