mod_delegation: use clean_xmlns to remove jabber:client namespace from node: for the same reason as in mod_privilege, `jabber:client` namespace is removed with the clean_xmlns method coming from there. Furthermore, the forwarded <iq> stanza use the `jabber:client` xmlns while the stanza may come from a component with e.g. `jabber:component:accept` xmlns, this can lead to inconsistencies between the <iq> stanza and children (like <error> element).

local disable_tls_ports = module:get_option_set("disable_tls_ports", {});

module:hook("stream-features", function (event)
	if disable_tls_ports:contains(event.origin.conn:serverport()) then
		module:log("error", "Disabling TLS for client on port %d", event.origin.conn:serverport());
		event.origin.conn.starttls = false;
	end
end, 1000);
