Note that the "new way" stuff is only for Zope *later* than 2.8.x.
In that case, you would define the function in a module somewhere on
your $PYTHONPATH (e.g., in $INSTANCE_HOME/lib/python, or in a product)
and then register it in a ZCML file which is included from your
'site.zcml' (in $INSTANCE_HOME/etc).
