I check a code for you and there are defaults defined for it: prod_dir -> `libzypp default` enable -> false autorefresh -> true priority -> `libzypp default` and checking also xml schema - https://github.com/yast/yast-installation-control/blob/master/control/control.rnc#L395 only base_urls is mandatory, so you should be fine to do not define it, if you are fine with defaults.
