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 st = require "util.stanza";

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

module:hook("csi-is-stanza-important", function (event)
	local stanza = event.stanza;
	if st.is_stanza(stanza) then
		for important in important_payloads do
			if stanza:find(important) then
				return true;
			end
		end
	end
end);
