Peter,

I'd say it's a version number for the configuration *format* itself and 
the corresponding parsing routines, which depend on m0n0wall version.

It's supposed to warn people when they mix config.xml versions and 
m0n0wall versions. For example:

"WARNING! The current configuration has been created with
a newer version of m0n0wall than this one! This can lead
to serious misbehavior and even security holes! You are
urged to either upgrade to a newer version of m0n0wall
or revert to the default configuration immediately!"

Take a look at /etc/inc/config.inc (function convert_config in particular).
