Like this:

      /* the {persistent} tag should be made optional (or at least
	 concealable) eventually */
      nameprop->string_data =
	  g_strdup_printf("%s {persistent}",
			  gschema_element->base_table_def_sql->table_sql->str);
      /* this compulsory capitalization of class-names-as-table-names
	 should be made optional eventually */
      nameprop->string_data[0] =
	  (char) toupper((int)
		 gschema_element->base_table_def_sql->table_sql->str[0]);
      g_strdown(nameprop->string_data + 1);

      umlclass_obj->ops->set_props(umlclass_obj, props);

      /* need some code here to fit the size of the class box to the
	 size of the class name (which doesn't happen automatically) a
	 la Properties->Apply button */
