http://xmpp.org/extensions/xep-0231.html#format indicates that the 'type' attribute is REQUIRED on the <data/> element, as does the XML schema section, but in the examples, it's only included on the returned data (which is sensible, a requesting client cannot know what the data actually is).
My opinion is that it's only required on the iq type=result, but I don't have good ideas on an updated schema/text to reflect that. ~Paul
