Unfortunately, the rules don't work as you may think. At the moment,
they are entirely informative with no code backing whatsoever. The
original intent was to develop code generation based on the rules, but
as I mentioned when Gianluigi first asked about model generation[1],
we are moving away from these mapping files and soon all code will be
generated directly from the XSD (http://www.ome-xml.org).

Although the XSD-based code generation has not yet been completed,
I'll remove the <rules/> elements to prevent further confusion. Sorry
for being misleading. The only way to extend the code generation at
the moment is by directly modifying the "dsl" component.
