ACK - this looks like a useful helper method for implementing _part_ of
the new functionality.  But if you make things more generic, you
probably also want a helper function at a higher level that delegates
between domain_conf.c, interface_conf.c, and so forth, all according to
the type parameter tied to the XML being normalized.
